109-544: Pulsar is a watch brand and currently a Seiko Watch Corporation of America (SCA) division. Pulsar was the world's first electronic digital watch. Current Pulsar watches are mostly analog and use the same movements in Seikos such as the 7T62 quartz chronograph movement. In 1970, Pulsar was a brand of the American Hamilton Watch Company which first announced that it was making and bringing

218-602: A "Watch Wristlet" design in 1893, but probably produced similar designs from the 1880s. Officers in the British Army began using wristwatches during colonial military campaigns in the 1880s, such as during the Anglo-Burma War of 1885. During the First Boer War of 1880–1881, the importance of coordinating troop movements and synchronizing attacks against highly mobile Boer insurgents became paramount, and

327-453: A 5 centimes coin; Zëhräppler for a 10 centimes coin; Zwänzgräppler for a 20 centimes coin; Stutz or Franke for a 1 franc coin or change in general; Füüfliiber for a 5 francs coin; Rappe and Batze are specifically used for coin below 1 franc, but also figuratively for change in general The Swiss franc , or simply the franc , is the currency and legal tender of Switzerland and Liechtenstein . It

436-566: A Russian-owned spread betting firm established in the UK, temporarily declared insolvency before announcing its desire to be acquired (and later denied rumours of an acquisition) by FXCM . FXCM was bailed out by its parent company. Saxo Bank of Denmark reported losses on 19 January 2015. New Zealand foreign exchange broker Global Brokers NZ announced it "could no longer meet New Zealand regulators' minimum capital requirements" and terminated its business. Coins before 1700 were based on either

545-462: A Swiss bank account. This devaluation of the euro against the franc was expected to hurt Switzerland's large export industry. The Swatch Group , for example, saw its shares drop 15% (in Swiss franc terms) with the announcements so that the share price may have increased on that day in terms of other major currencies. The large and unexpected jump caused major losses for some currency traders. Alpari ,

654-572: A blend of both. Most watches intended mainly for timekeeping today have electronic movements, with mechanical hands on the watch face indicating the time. Compared to electronic movements, mechanical watches are less accurate, often with errors of seconds per day; are sensitive to position, temperature, and magnetism; are costly to produce; require regular maintenance and adjustments; and are more prone to failures. Nevertheless, mechanical watches attract interest from consumers, particularly among watch collectors. Skeleton watches are designed to display

763-424: A decade – almost 100 years of dominance by the mechanical wristwatch legacy. Modern quartz movements are produced in very large quantities, and even the cheapest wristwatches typically have quartz movements. Whereas mechanical movements can typically be off by several seconds a day, an inexpensive quartz movement in a child's wristwatch may still be accurate to within half a second per day – ten times more accurate than

872-472: A frequent confusion with the 100-franc note, and that the 10-franc note was changed from red to yellow. The size of the notes was changed as well, with all notes from the eighth series having the same height (74 mm), while the widths were changed as well, still increasing with the value of the notes. The new series contain many more security features than the previous ones; many of them are now visibly displayed and have been widely advertised, in contrast with

981-830: A gold-selling program, the Swiss National Bank held 1,290 tonnes of gold in reserves, which equated to 20% of its assets. In November 2014, the referendum on the "Swiss Gold Initiative", which proposed a restoration of 20% gold backing for the Swiss franc, was voted down. The onset of the Greek sovereign debt crisis resulted in a strong appreciation in the value of the Swiss franc, past US$ 1.10 (CHF 0.91 per USD) in March 2011, to US$ 1.20 (CHF 0.833 per USD) in June 2011, and to US$ 1.30 (CHF 0.769 per USD) in August 2011. This prompted

1090-424: A leather strap, but by the early 20th century, manufacturers began producing purpose-built wristwatches. The Swiss company Dimier Frères & Cie patented a wristwatch design with the now standard wire lugs in 1903. In 1904, Louis Cartier produced a wristwatch to allow his friend Alberto Santos-Dumont to check flight performance in his airship while keeping both hands on the controls as this proved difficult with

1199-478: A line of wristwatches. The impact of the First World War of 1914–1918 dramatically shifted public perceptions on the propriety of the man's wristwatch and opened up a mass market in the postwar era. The creeping barrage artillery tactic, developed during the war, required precise synchronization between the artillery gunners and the infantry advancing behind the barrage. Service watches produced during

1308-492: A manner analogous to the pendulum of a pendulum clock . The tourbillon , an optional part for mechanical movements, is a rotating frame for the escapement, used to cancel out or reduce gravitational bias. Due to the complexity of designing a tourbillon, they are expensive, and typically found in prestigious watches. The pin-lever escapement (called the Roskopf movement after its inventor, Georges Frederic Roskopf ), which

1417-680: A mechanical movement. After a consolidation of the mechanical watch industry in Switzerland during the 1970s, mass production of quartz wristwatches took off under the leadership of the Swatch Group of companies, a Swiss conglomerate with vertical control of the production of Swiss watches and related products. For quartz wristwatches, subsidiaries of Swatch manufacture watch batteries ( Renata ), oscillators ( Oscilloquartz , now Micro Crystal AG) and integrated circuits (Ebauches Electronic SA, renamed EM Microelectronic-Marin ). The launch of

1526-404: A monetary concordate , issuing standardised coins, the so-called Konkordanzbatzen , still carrying the coat of arms of the issuing canton, but interchangeable and identical in value. The reverse side of the coin displayed a Swiss cross with the letter C in the center. The Konkordanzbatzen among the Swiss cantons agreeing on an exclusive issue of currency in francs and batzen failed to replace

1635-407: A pocket watch. Cartier still markets a line of Santos-Dumont watches and sunglasses. In 1905, Hans Wilsdorf moved to London, and set up his own business, Wilsdorf & Davis, with his brother-in-law Alfred Davis, providing quality timepieces at affordable prices; the company became Rolex in 1915. Wilsdorf was an early convert to the wristwatch, and contracted the Swiss firm Aegler to produce

1744-700: A replaceable battery . The first use of electrical power in watches was as a substitute for the mainspring, to remove the need for winding. The first electrically powered watch, the Hamilton Electric 500, was released in 1957 by the Hamilton Watch Company of Lancaster, Pennsylvania . Watch batteries (strictly speaking cells, as a battery is composed of multiple cells) are specially designed for their purpose. They are very small and provide tiny amounts of power continuously for very long periods (several years or more). In most cases, replacing

1853-549: A self-winding system as a separate module that could be used with almost any 8.75 ligne (19.74 millimeter) watch movement. Glycine incorporated this module into its watches in October 1930, and began mass-producing automatic watches. The Elgin National Watch Company and the Hamilton Watch Company pioneered the first electric watch . The first electric movements used a battery as a power source to oscillate

1962-400: A specific highly stable frequency, which is used to accurately pace a timekeeping mechanism. Most quartz movements are primarily electronic but are geared to drive mechanical hands on the face of the watch to provide a traditional analog display of the time, a feature most consumers still prefer. In 1959 Seiko placed an order with Epson (a subsidiary company of Seiko and the 'brain' behind

2071-431: A winding, requiring winding daily, some run for several days; a few have 192-hour mainsprings, requiring once-weekly winding. A self-winding or automatic watch is one that rewinds the mainspring of a mechanical movement by the natural motions of the wearer's body. The first self-winding mechanism was invented for pocket watches in 1770 by Abraham-Louis Perrelet, but the first " self-winding ", or "automatic", wristwatch

2180-400: A wrist. They generally incorporate timekeeping functions, but these are only a small subset of the smartwatch's facilities. In general, modern watches often display the day, date, month, and year. For mechanical watches, various extra features called " complications ", such as moon-phase displays and the different types of tourbillon , are sometimes included. Most electronic quartz watches, on

2289-402: A wristwatch, described as an "armed watch", from Robert Dudley . The oldest surviving wristwatch (then described as a "bracelet watch") is one made in 1806, and given to Joséphine de Beauharnais . From the beginning, wristwatches were almost exclusively worn by women – men used pocket watches up until the early 20th century. In 1810, the watch-maker Abraham-Louis Breguet made a wristwatch for

2398-440: Is a cheaper version of the fully levered movement, was manufactured in huge quantities by many Swiss manufacturers, as well as by Timex , until it was replaced by quartz movements. Introduced by Bulova in 1960, tuning-fork watches use a type of electromechanical movement with a precise frequency (most often 360 Hz ) to drive a mechanical watch. The task of converting electronically pulsed fork vibration into rotary movements

2507-419: Is a fusion between a regular mechanical watch and a smartwatch. The movement and case are the basic parts of a watch. A watch band or bracelet is added to form a wristwatch; alternatively, a watch chain is added to form a pocket watch. The case is the outer covering of the watch. The case back is the back portion of the watch's case. Accessing the movement (such as during battery replacement) depends on

2616-645: Is also legal tender in the Italian exclave of Campione d'Italia which is surrounded by Swiss territory. The Swiss National Bank (SNB) issues banknotes and the federal mint Swissmint issues coins . It is also designated through currency signs Fr. (in German language ), fr. (in French , Italian , Romansh languages ), as well as in any other language, or internationally as CHF which stands for Confoederatio Helvetica Franc. This acronym also serves as

2725-630: Is claimed to be accurate to +/− 10 seconds a year and has a smooth sweeping second hand rather than one that jumps each second. Radio time signal watches are a type of electronic quartz watch that synchronizes ( time transfers ) its time with an external time source such as in atomic clocks , time signals from GPS navigation satellites, the German DCF77 signal in Europe, WWVB in the US, and others. Movements of this type may, among others, synchronize

2834-401: Is designed for a person to carry in a pocket , often attached to a chain. Watches appeared in the 16th century. During most of its history, the watch was a mechanical device, driven by clockwork , powered by winding a mainspring , and keeping time with an oscillating balance wheel . These are called mechanical watches . In the 1960s the electronic quartz watch was invented, which

2943-474: Is done via two tiny jeweled fingers, called pawls. Tuning-fork watches were rendered obsolete when electronic quartz watches were developed. Traditional mechanical watch movements use a spiral spring called a mainspring as its power source that must be rewound periodically by the user by turning the watch crown. Antique pocket watches were wound by inserting a key into the back of the watch and turning it. While most modern watches are designed to run 40 hours on

3052-485: Is used for language-neutral inscriptions on its coins. Before 1798, about 75 entities were making coins in Switzerland, including the 25 cantons and half-cantons, 16 cities, and abbeys, resulting in about 860 different coins in circulation, with different values, denominations and monetary systems. However, the origins of a majority of these currencies can be traced to either the French livre tournois (the predecessor of

3161-560: The florin petite monnaie , with 3 + 1 ⁄ 2 florins equal to the livre courant . After 1641, the Spanish dollar was worth 10 + 1 ⁄ 2 florins or 3 livres. Afterwards, the écu was valued at 12 + 3 ⁄ 4 florins or 3 + 9 ⁄ 14 livres, while the kronenthaler was valued at 12 + 3 ⁄ 8 florins or 3 + 15 ⁄ 28 livres. See also Geneva thaler and Geneva genevoise . Many currencies of central and eastern Switzerland originated from

3270-467: The Bretton Woods system with its exchange rate to the dollar fixed until 1970. The Swiss franc has historically been considered a safe-haven currency , with a legal requirement that a minimum of 40% be backed by gold reserves . However, this link to gold, which dated from the 1920s, was terminated on 1 May 2000 following a referendum , making the franc fiat money . By March 2005, following

3379-532: The Deutsche mark and maintained it, although at the cost of high inflation. Until mid-January 2015, the franc continued to trade below the target level set by the SNB, though the ceiling was broken at least once on 5 April 2012, albeit briefly. On 18 December 2014, the Swiss central bank introduced a negative interest rate on bank deposits to support its CHF ceiling. However, with the euro declining in value over

3488-525: The Federal Council (cabinet) and National Bank proposed in April 2017 to remove the time limit on exchanges for the sixth and future recalled series. As of 2020, this proposal was enacted, so old banknote series will not expire. The seventh series was printed in 1984, but kept as a "reserve series", ready to be used if, for example, wide counterfeiting of the current series suddenly happened. When

3597-640: The French franc ) or the South German gulden of the 17th century. The new Swiss currencies emerged in the 18th century after Swiss cantons did not follow the pace of depreciations which occurred in France and Germany. However, they mostly existed only in small change as they were little more than community currency , current in one canton but not in the other, and foreign coins like French francs and kronenthalers were more recognized as currency all over Switzerland. A high-level summary of existing currencies at

3706-657: The ISO 4217 currency code, used by banks and financial institutions. The smaller denomination, a hundredth of a franc, is a Rappen (Rp.) in German, centime (c.) in French, centesimo (ct.) in Italian, and rap (rp.) in Romansh. The official symbols Fr. (German symbol) and fr. (Latin languages) are widely used by businesses and advertisers, also for the English language. According to Art. 1 SR/RS 941.101 of

3815-537: The Mediation period (1803–1814). These 19 cantonal currencies were the Appenzell frank , Argovia frank , Basel frank , Berne frank , Fribourg frank , Geneva franc , Glarus frank , Graubünden frank , Luzern frank , St. Gallen frank , Schaffhausen frank , Schwyz frank , Solothurn frank , Thurgau frank , Ticino franco , Unterwalden frank , Uri frank , Vaud franc , and Zürich frank . After 1815,

3924-643: The Observatory of Neuchâtel in 1967. In 1970, 18 manufacturers exhibited production versions of the beta 21 wristwatch, including the Omega Electroquartz as well as Patek Philippe , Rolex Oysterquartz and Piaget . The first quartz watch to enter production was the Seiko 35 SQ Astron , which hit the shelves on 25 December 1969, swiftly followed by the Swiss Beta 21, and then a year later

4033-443: The South German gulden . It was divided into 40 schilling or 60 kreuzer , and the thaler was worth 2 gulden. After 1690, this gulden was worth 1 ⁄ 2 a Reichsthaler specie, or 12.992 g fine silver. After 1730, the different guilders of Southern Germany and Switzerland fragmented under varying rates of depreciation. The South German gulden , worth 1 ⁄ 24 a Cologne mark (233.856 g) of fine silver, also applied to

4142-545: The Swiss National Bank took over the issuance of banknotes from the cantons and various banks. It introduced denominations of 50, 100, 500 and 1000 francs. Twenty-franc notes were introduced in 1911, followed by 5-franc notes in 1913. In 1914, the Federal Treasury issued paper money in denominations of 5, 10 and 20 francs. These notes were issued in three different versions: French, German and Italian. The State Loan Bank also issued 25-franc notes that year. In 1952,

4251-545: The franc or frank , modelled on the Bern livre worth 1 ⁄ 4 the écu, subdivided into 10 batzen or 100 rappen (centimes) . It contained 6 + 2 ⁄ 3 grams of fine silver and was initially worth 1 + 1 ⁄ 2 livres tournois or 1.48 French francs . This franc was issued until the end of the Helvetic Republic in 1803, but served as the model for the currencies of several cantons in

4360-904: The most expensive watch ever sold at auction was the Patek Philippe Henry Graves Supercomplication , the world's most complicated mechanical watch until 1989, fetching US$ 24 million ( CHF 23,237,000) in Geneva on 11 November 2014. As of December 2019, the most expensive watch ever sold at auction (and wristwatch) was the Patek Philippe Grandmaster Chime Ref. 6300A-010, fetching US$ 31.19 million (CHF 31,000,000) in Geneva on 9 November 2019. Watches evolved from portable spring-driven clocks, which first appeared in 15th-century Europe. The first timepieces to be worn, made in

4469-655: The quartz watch in 1969 in the form of the Seiko Astron 35SQ , and in 1970 in the form of the Omega Beta 21 was a revolutionary improvement in watch technology. In place of a balance wheel, which oscillated at perhaps 5 or 6 beats per second, these devices used a quartz-crystal resonator , which vibrated at 8,192 Hz, driven by a battery-powered oscillator circuit . Most quartz-watch oscillators now operate at 32,768 Hz, though quartz movements have been designed with frequencies as high as 262 kHz. Since

4578-468: The restored Swiss Confederacy attempted to simplify the system of currencies once again. As of 1820, a total of 8,000 distinct coins were current in Switzerland: those issued by cantons, cities, abbeys, and principalities or lordships, mixed with surviving coins of the Helvetic Republic and the pre-1798 Helvetic Republic. In 1825, the cantons of Bern, Basel, Fribourg, Solothurn, Aargau, and Vaud formed

4687-547: The 10-franc note (18 October 2017), the 200-franc note (15 August 2018), the 1000-franc note (5 March 2019), and the 100-franc note (12 September 2019). All banknotes from the eighth series were withdrawn on 30 April 2021, but, like banknotes of the sixth series withdrawn in 2000, remain indefinitely redeemable at the Swiss National Bank. The Swiss franc is the currency and legal tender of Switzerland and Liechtenstein and also legal tender in

4796-442: The 16th century beginning in the German cities of Nuremberg and Augsburg , were transitional in size between clocks and watches. Nuremberg clockmaker Peter Henlein (or Henle or Hele) (1485–1542) is often credited as the inventor of the watch. However, other German clockmakers were creating miniature timepieces during this period, and there is no evidence Henlein was the first. Watches were not widely worn in pockets until

4905-468: The 17th century. One account suggests that the word "watch" came from the Old English word woecce – which meant "watchman" – because town watchmen used the technology to keep track of their shifts at work. Another says that the term came from 17th-century sailors, who used the new mechanisms to time the length of their shipboard watches (duty shifts). A rise in accuracy occurred in 1657 with

5014-468: The 1980s, more quartz watches than mechanical ones have been marketed. The Timex Datalink wristwatch was introduced in 1994. The early Timex Datalink Smartwatches realized a wireless data transfer mode to receive data from a PC. Since then, many companies have released their own iterations of a smartwatch, such as the Apple Watch , Samsung Galaxy Watch , and Huawei Watch . A hybrid smartwatch

5123-597: The 23rd canton of the Swiss Confederation. The 10 centime coins from 1879 onwards (except the years 1918–19 and 1932–1939) have had the same composition, size, and design to present and are still legal tender and found in circulation. For this, the coin entered the Guinness Book of Records as the oldest original currency in circulation. All Swiss coins are language-neutral with respect to Switzerland's four national languages, featuring only numerals,

5232-463: The 5 centime and 10 centime coins and by nickel in the 20 centime piece. Gold coins in denominations of 10, 20, and 100 francs, known as Vreneli , circulated until 1936. Both world wars only had a small effect on the Swiss coinage, with brass and zinc coins temporarily being issued. In 1931, the mass of the 5 franc coin was reduced from 25 grams to 15, with the silver content reduced to .835 fineness. The next year, nickel replaced cupronickel in

5341-404: The 5 centime and 10 centime coins. In the late 1960s, the prices of internationally traded commodities rose significantly. A silver coin's metal value exceeded its monetary value, and many were being sent abroad for melting, which prompted the federal government to make this practice illegal. The statute was of little effect, and the melting of francs only subsided when the collectible value of

5450-414: The 5 centimes, 10 centime and 20 centime in billon (with 5% to 15% silver content); and the 1 ⁄ 2 franc, 1 franc, 2 franc and 5 franc in .900 fine silver . Between 1860 and 1863, .800 fine silver was used, before the standard used in France of .835 fineness was adopted for all silver coins except the 5 francs (which remained .900 fineness) in 1875. In 1879, billon was replaced by cupronickel in

5559-461: The 5 francs coins in 1888, 1922, 1924 (minor), and 1931 (mostly just a size reduction). A new design for the bronze coins was used from 1948. Coins depicting a ring of stars (such as the 1 franc coin seen beside this paragraph) were altered from 22 stars to 23 stars in 1983; since the stars represent the Swiss cantons, the design was updated when in 1979 Jura seceded from the Canton of Bern and became

5668-699: The CEH research laboratory in Neuchâtel , Switzerland. From 1965 through 1967 pioneering development work was done on a miniaturized 8192 Hz quartz oscillator, a thermo-compensation module, and an in-house-made, dedicated integrated circuit (unlike the hybrid circuits used in the later Seiko Astron wristwatch). As a result, the BETA 1 prototype set new timekeeping performance records at the International Chronometric Competition held at

5777-1257: The French livre tournois system (in Louis d'Argent, Louis d'Or and fractions) or the South German gulden system (in Reichsthalers , florins and fractions). After 1700 Swiss cantonal currencies diverged from the value of the French and German units. However, they mostly existed only in small change as they were a mere community currency, current in one canton but not in the other, and foreign coins like French francs and Brabant dollars were more recognized as currency all over Switzerland. Between 1798 and 1803, billon coins were issued in denominations of 1 centime, 1 ⁄ 2 batzen, and 1 batzen. Silver coins were issued for 10, 20 and 40 batzen (also denominated 4 francs), matching with French coins worth 1 ⁄ 4 , 1 ⁄ 2 and 1 écu. Gold 16- and 32-franc coins were issued in 1800, also matching with French coins worth 24 and 48 livres tournois. In 1850, coins were introduced in denominations of 1 centime , 2 centimes , 5 centimes , 10 centimes 20 centimes , 1 ⁄ 2 franc , 1 franc , 2 francs , and 5 francs . The 1 centime and 2 centime coins were struck in bronze;

5886-535: The LED watch to market. It was developed jointly by American companies Hamilton and Electro/Data Inc. In the spring of 1972, the first Pulsar watch was marketed by Hamilton Watch (the parent company, not the Hamilton Watch Division). With an 18-carat gold case, the world's first all-electronic digital watch was also the first to use a digital display created with light-emitting diodes (LEDs). A button

5995-537: The Queen of Naples. The first Swiss wristwatch was made in the year 1868 by the Swiss watch-maker Patek Philippe for Countess Koscowicz of Hungary. Wristwatches were first worn by military men towards the end of the 19th century, having increasingly recognized the importance of synchronizing maneuvers during war without potentially revealing plans to the enemy through signaling. The Garstin Company of London patented

6104-401: The Swiss National Bank decided to develop new security features and to abandon the concept of a reserve series, the details of the seventh series were released and the printed notes were destroyed. The eighth series of banknotes was designed by Jörg Zintzmeyer  [ de ] around the theme of the arts and released starting in 1995. In addition to its new vertical design, this series

6213-457: The Swiss National Bank to boost the franc's liquidity to try to counter its "massive overvaluation ". The Economist argued that its Big Mac Index in July 2011 indicated an overvaluation of 98% over the dollar, and cited Swiss companies releasing profit warnings and threatening to move operations out of the country due to the strength of the franc. Demand for francs and franc-denominated assets

The cantons of Zurich, Schwyz and Glarus, however, maintained a stronger gulden worth 1 ⁄ 22 a Cologne mark of fine silver. The French écu was valued at 2 + 1 ⁄ 2 gulden, while the kronenthaler

6431-484: The United Kingdom. Watch A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist , attached by a watch strap or other type of bracelet , including metal bands, leather straps, or any other kind of bracelet. A pocket watch

6540-726: The abbreviation "Fr." for franc, and the Latin phrases Helvetia or Confœderatio Helvetica (depending on the denomination) or the inscription Libertas (Roman goddess of liberty) on the small coins. The name of the artist is present on the coins with the standing Helvetia and the herder. In addition to these general-circulation coins, numerous series of commemorative coins have been issued, as well as silver and gold coins. These coins are no longer legal tender, but can in theory be exchanged at face value at post offices, and at national and cantonal banks, although their metal or collectors' value equals or exceeds their face value. In 1907,

6649-433: The actual face value of the coin for many years. The coin fell into disuse in the late 1970s and early 1980s, but was only officially fully withdrawn from circulation and declared to be no longer legal tender on 1 January 2007. The long-forgotten 2 centime coin, not minted since 1974, was demonetized on 1 January 1978. The designs of the coins have changed very little since 1879. Among the notable changes were new designs for

6758-498: The addition of the balance spring to the balance wheel, an invention disputed both at the time and ever since between Robert Hooke and Christiaan Huygens . This innovation increased watches' accuracy enormously, reducing error from perhaps several hours per day to perhaps 10 minutes per day, resulting in the addition of the minute hand to the face from around 1680 in Britain and around 1700 in France. The increased accuracy of

6867-685: The application of duplicating tools and machinery in 1843. In the United States , Aaron Lufkin Dennison started a factory in 1851 in Massachusetts that used interchangeable parts , and by 1861 a successful enterprise operated, incorporated as the Waltham Watch Company . The concept of the wristwatch goes back to the production of the very earliest watches in the 16th century. In 1571, Elizabeth I of England received

6976-494: The balance assembly delivered the power to the balance wheel. Similar designs from many other watch companies followed. Another type of electric watch was developed by the Bulova company that used a tuning-fork resonator instead of a traditional balance wheel to increase timekeeping accuracy, moving from a typical 2.5–4 Hz with a traditional balance wheel to 360 Hz with the tuning-fork design. The commercial introduction of

7085-525: The balance wheel and the escapement for accuracy by laser . The low parts count and the fully automated assembly make it an inexpensive automatic Swiss watch. Electronic movements, also known as quartz movements, have few or no moving parts, except a quartz crystal which is made to vibrate by the piezoelectric effect . A varying electric voltage is applied to the crystal, which responds by changing its shape so, in combination with some electronic components, it functions as an oscillator . It resonates at

7194-409: The balance wheel focused attention on errors caused by other parts of the movement , igniting a two-century wave of watchmaking innovation. The first thing to be improved was the escapement . The verge escapement was replaced in quality watches by the cylinder escapement , invented by Thomas Tompion in 1695 and further developed by George Graham in the 1720s. Improvements in manufacturing – such as

7303-482: The balance wheel. During the 1950s, Elgin developed the model 725, while Hamilton released two models: the first, the Hamilton 500, released on 3 January 1957, was produced into 1959. This model had problems with the contact wires misaligning, and the watches returned to Hamilton for alignment. The Hamilton 505, an improvement on the 500, proved more reliable: the contact wires were removed and a non-adjustable contact on

7412-420: The battery requires a trip to a watch-repair shop or watch dealer; this is especially true for watches that are water-resistant, as special tools and procedures are required for the watch to remain water-resistant after battery replacement. Silver-oxide and lithium batteries are popular today; mercury batteries, formerly quite common, are no longer used, for environmental reasons. Cheap batteries may be alkaline, of

7521-414: The close of trading that day, the franc was up 23% against the euro and 21% against the US dollar. The full daily appreciation of the franc was equivalent to $ 31,000 per single futures contract: more than the market had moved collectively in the previous thousand days. The key CHF interest rate was also lowered from −0.25% to −0.75%, meaning depositors would be paying an increased fee to keep their funds in

7630-500: The decades progressed and the efficiency of the solar cells increased while the power requirements of the movement and display decreased, solar watches began to be designed to look like other conventional watches. A rarely used power source is the temperature difference between the wearer's arm and the surrounding environment (as applied in the Citizen Eco-Drive Thermo). Swiss franc Füfräppler for

7739-501: The end of the 18th century is shown below, including their equivalents in terms of the French écu of 26.67 g fine silver, the South German kronenthaler of 25.71 g fine silver, and Swiss francs of 4.5 g fine silver. The livre of Bern and most western Swiss cantons like Basel, Aargau, Fribourg, Vaud, Valais, Lausanne, Neuchâtel and Solothurn originated from the French livre tournois . Geneva had its own currency,

7848-468: The federal law collection the internationally official abbreviation – besides the national languages – however is CHF , also in English; respective guides also request to use the ISO ;4217 code. The use of SFr. for Swiss Franc and fr.sv. are outdated. As previously indicated Latinate "CH" stands for Confoederatio Helvetica ; given the different languages used in Switzerland , Latin

7957-406: The following weeks, in a move dubbed Francogeddon for its effect on markets, the Swiss National Bank abandoned the ceiling on 15 January 2015, and the franc promptly increased in value compared with the euro by 30%, although this only lasted a few minutes before part of the increase was reversed. The move was not announced in advance and resulted in "turmoil" in stock and currency markets. By

8066-409: The franc as the monetary unit of Switzerland. The Swiss franc was introduced at par with the French franc , at 4.5 g fine silver or 9 ⁄ 31 g = 0.29032 g fine gold (ratio 15.5). The currencies of the Swiss cantons were converted to Swiss francs by first restating their equivalents in German kronenthaler ( écu brabant ) of 25 + 5 ⁄ 7 grams fine silver, and then to Swiss francs at

8175-407: The franc fell against the euro from 1.11 to 1.20 CHF, against the U.S. dollar from 0.787 to 0.856 CHF, and against all 16 of the most active currencies on the same day. It was the largest plunge of the franc ever against the euro. The intervention stunned currency traders, since the franc had long been regarded as a safe haven. The SNB had previously set an exchange rate target in 1978 against

8284-405: The mechanism for aesthetic purposes. A mechanical movement uses an escapement mechanism to control and limit the unwinding and winding parts of a spring, converting what would otherwise be a simple unwinding into a controlled and periodic energy release. The movement also uses a balance wheel , together with the balance spring (also known as a hairspring), to control the gear system's motion in

8393-544: The monetary union faded away in the 1920s and officially ended in 1927, the Swiss franc remained on that standard until 27 September 1936, when it suffered its sole devaluation during the Great Depression . Following the devaluations of the British pound , U.S. dollar and French franc , the Swiss franc was devalued 30% to 0.20322 grams fine gold, equivalent to US$ 1 = CHF 4.37295. In 1945, Switzerland joined

8502-479: The national bank ceased issuing 5-franc notes but introduced 10-franc notes in 1955. In 1996, 200-franc notes were introduced whilst the 500-franc note was discontinued. Nine series of banknotes have been printed by the Swiss National Bank, seven of which have been released for use by the general public, the fourth and seventh being reserved and never issued. The sixth series from 1976, designed by Ernst and Ursula Hiestand  [ de ] , depicted persons from

8611-670: The new SWATCH brand in 1983 was marked by bold new styling, design, and marketing. Today, the Swatch Group maintains its position as the world's largest watch company. Seiko 's efforts to combine the quartz and mechanical movements bore fruit after 20 years of research, leading to the introduction of the Seiko Spring Drive , first in a limited domestic market production in 1999 and to the world in September 2005. The Spring Drive keeps time within quartz standards without

8720-718: The other hand, include time-related features such as timers , chronographs , and alarm functions. Furthermore, some modern watches (like smart watches) even incorporate calculators , GPS and Bluetooth technology or have heart-rate monitoring capabilities, and some of them use radio clock technology to regularly correct the time. Most watches that are used mainly for timekeeping have quartz movements. However, expensive collectible watches, valued more for their elaborate craftsmanship, aesthetic appeal, and glamorous design than for simple timekeeping, often have traditional mechanical movements, despite being less accurate and more expensive than their electronic counterparts. As of 2018,

8829-448: The over 8,000 different coins and notes in circulation. Despite introduction of the first Swiss franc, the South German kronenthaler became the more desirable coin to use in the 19th century, and it was still quoted in pre-1798 currency equivalents. Furthermore, less than 15% of Swiss money in circulation was in local currency, since French and German gold and silver trade coins proved to be more desirable means of exchange. A final problem

8938-510: The picture. The reverse has the other two languages. When the fifth series lost its validity at the end of April 2000, the banknotes that had not been exchanged represented a total value of 244.3 million Swiss francs; in accordance with Swiss law, this amount was transferred to the Swiss Fund for Emergency Losses in the Case of Non-insurable Natural Disasters. In February 2005, a competition

9047-400: The previous series for which most of the features were kept secret. All banknotes are quadrilingual, displaying all information in the four national languages. With the eighth series, the banknotes depicting a Germanophone person have German and Romansch on the same side as the picture, whereas banknotes depicting a Francophone or an Italophone person have French and Italian on the same side as

9156-479: The prototype of one of the world's most accurate wristwatches to date: the Omega Marine Chronometer . Since the technology having been developed by contributions from Japanese, American and Swiss, nobody could patent the whole movement of the quartz wristwatch, thus allowing other manufacturers to participate in the rapid growth and development of the quartz watch market. This ended – in less than

9265-540: The quartz revolution) to start developing a quartz wristwatch. The project was codenamed 59A. By the 1964 Tokyo Summer Olympics , Seiko had a working prototype of a portable quartz watch which was used as the time measurements throughout the event. The first prototypes of an electronic quartz wristwatch (not just portable quartz watches as the Seiko timekeeping devices at the Tokyo Olympics in 1964) were made by

9374-495: The rate of 7 écu brabant = 40 Swiss francs. The first franc worth 1 ⁄ 4 th the French écu was converted at 1.4597 Swiss francs. In 1865, France , Belgium , Italy , and Switzerland formed the Latin Monetary Union , in which they agreed to value their national currencies to a standard of 4.5 grams of fine silver or 0.290322 grams fine gold, equivalent to US$ 1 = CHF 5.1826 until 1934. Even after

9483-569: The rechargeable battery or capacitor. As long as the watch is regularly exposed to fairly strong light (such as sunlight), it never needs a battery replacement. Some models need only a few minutes of sunlight to provide weeks of energy (as in the Citizen Eco-Drive ). Some of the early solar watches of the 1970s had innovative and unique designs to accommodate the array of solar cells needed to power them (Synchronar, Nepro, Sicura, and some models by Cristalonic, Alba , Seiko, and Citizen). As

9592-417: The remaining francs again exceeded their material value. The 1 centime coin was still produced until 2006, albeit in ever decreasing quantities, but its importance declined. Those who could justify the use of 1 centime coins for monetary purposes could obtain them at face value; any other user (such as collectors) had to pay an additional four centimes per coin to cover the production costs, which had exceeded

9701-405: The same size as silver-oxide cells but providing shorter life. Rechargeable batteries are used in some solar-powered watches . Some electronic watches are powered by the movement of the wearer. For instance, Seiko's kinetic-powered quartz watches use the motion of the wearer's arm: turning a rotating weight which causes a tiny generator to supply power to charge a rechargeable battery that runs

9810-492: The single most important technological breakthrough, though invented by Thomas Mudge in 1754 and improved by Josiah Emery in 1785, only gradually came into use from about 1800 onwards, chiefly in Britain. The British predominated in watch manufacture for much of the 17th and 18th centuries, but maintained a system of production that was geared towards high-quality products for the élite. The British Watch Company modernized clock manufacture with mass-production techniques and

9919-406: The time of day and the date, the leap-year status and the state of daylight saving time (on or off). However, other than the radio receiver, these watches are normal quartz watches in all other aspects. Electronic watches require electricity as a power source, and some mechanical movements and hybrid electronic-mechanical movements also require electricity. Usually, the electricity is provided by

10028-515: The tooth-cutting machine devised by Robert Hooke – allowed some increase in the volume of watch production, although finishing and assembling was still done by hand until well into the 19th century. A major cause of error in balance-wheel timepieces, caused by changes in elasticity of the balance spring from temperature changes, was solved by the bimetallic temperature-compensated balance wheel invented in 1765 by Pierre Le Roy and improved by Thomas Earnshaw (1749–1829). The lever escapement ,

10137-416: The type of case back, which are generally categorized into four types: The crystal, also called the window or watch glass, is the transparent part of the case that allows viewing the hands and the dial of the movement. Modern wristwatches almost always use one of 4 materials: The bezel is the ring holding the crystal in place. The lugs are small metal projections at both ends of the wristwatch case where

10246-487: The use of a battery, using a traditional mechanical gear train powered by a spring, without the need for a balance wheel either. In 2010, Miyota ( Citizen Watch ) of Japan introduced a newly developed movement that uses a 3-pronged quartz crystal that was exclusively produced for Bulova to be used in the Precisionist or Accutron II line, a new type of quartz watch with ultra-high frequency (262.144 kHz) which

10355-633: The use of wristwatches subsequently became widespread among the officer class. The company Mappin & Webb began production of their successful "campaign watch" for soldiers during the campaign in the Sudan in 1898 and accelerated production for the Second Boer War of 1899–1902 a few years later. In continental Europe, Girard-Perregaux and other Swiss watchmakers began supplying German naval officers with wristwatches in about 1880. Early models were essentially standard pocket-watches fitted to

10464-483: The war were specially designed for the rigors of trench warfare , with luminous dials and unbreakable glass. The UK War Office began issuing wristwatches to combatants from 1917. By the end of the war, almost all enlisted men wore a wristwatch (or wristlet ), and after they were demobilized, the fashion soon caught on: the British Horological Journal wrote in 1917, that "the wristlet watch

10573-412: The watch band attaches to the watch case. The case and the lugs are often machined from one solid piece of stainless steel. The movement of a watch is the mechanism that measures the passage of time and displays the current time (and possibly other information including date, month, and day). Movements may be entirely mechanical, entirely electronic (potentially with no moving parts), or they might be

10682-402: The watch. The concept is similar to that of self-winding spring movements, except that electrical power is generated instead of mechanical spring tension. Solar powered watches are powered by light. A photovoltaic cell on the face ( dial ) of the watch converts light to electricity, which is used to charge a rechargeable battery or capacitor . The movement of the watch draws its power from

10791-449: The wearer's wrist motions are inadequate to keep the watch wound. In April 2013, the Swatch Group launched the sistem51 wristwatch. It has a mechanical movement consisting of only 51 parts, including 19 jewels and a novel self-winding mechanism with a transparent oscillating weight. Ten years after its introduction, it is still the only mechanical movement manufactured entirely on a fully automated assembly line, including adjustment of

10900-733: The world of science . This series was recalled on 1 May 2000 and is no longer legal tender, but notes can still be exchanged for valid ones of the same face value at any National Bank branch or authorized agent, or mailed in by post to the National Bank in exchange for a bank account deposit. The exchange program originally was due to end on 30 April 2020, after which sixth-series notes would lose all value. As of 2016, 1.1 billion francs' worth of sixth-series notes had not yet been exchanged, even though they had not been legal tender for 16 years and only 4 more years remained to exchange them. To avoid having to expire such large amounts of money in 2020,

11009-480: Was announced for the design of the ninth series, then planned to be released around 2010 on the theme "Switzerland open to the world". The results were announced in November 2005. The National Bank selected the designs of Swiss graphic designer Manuela Pfrunder as the basis of the new series. The first denomination to be issued was the 50-franc note on 12 April 2016. It was followed by the 20-franc note (17 May 2017),

11118-419: Was different from the previous one on several counts. Probably the most important difference from a practical point of view was that the seldom-used 500-franc note was replaced by a new 200-franc note; this new note has indeed proved more successful than the old 500-franc note. The base colours of the new notes were kept similar to the old ones, except that the 20-franc note was changed from blue to red to prevent

11227-463: Was little used by the sterner sex before the war, but now is seen on the wrist of nearly every man in uniform and of many men in civilian attire." By 1930, the wristwatch vastly exceeded the pocket watch in market share by a decisive ratio of 50:1. John Harwood invented the first successful self-winding system in 1923. In anticipation of Harwood's patent for self-winding mechanisms expiry in 1930, Glycine founder Eugène Meylan started development on

11336-462: Was powered by a battery and kept time with a vibrating quartz crystal . By the 1980s the quartz watch had taken over most of the market from the mechanical watch. Historically, this is called the quartz revolution (also known as the quartz crisis in Switzerland ). Developments in the 2010s include smart watches , which are elaborate computer-like electronic devices designed to be worn on

11445-538: Was pressed to display the time. The first Pulsar initially sold for $ 2,100 ($ 15,800 in 2023 dollars). In October 1972, the Potpourri segment in the issue of Playboy mentioned the first Pulsar, and included a photo. In 1975, a digital Pulsar with a built-in calculator was released. In 1978, Seiko Corporation acquired the Pulsar brand, it is mid-grade of their product range. By 2020, Seiko had ceased selling its Pulsar in

11554-464: Was so strong that nominal short-term Swiss interest rates became negative. On 6 September 2011, the day after the franc traded at 1.11 CHF/ € and appeared headed to parity with the euro , the SNB set a minimum exchange rate of 1.20 CHF to the euro ('capping' the franc's appreciation), saying "the value of the franc is a threat to the economy", and that it was "prepared to buy foreign currency in unlimited quantities". In response to this announcement

11663-487: Was that the first Swiss franc was based on the French écu which was being phased out by France in the 19th century. To solve this problem, the new Swiss Federal Constitution of 1848 specified that the federal government would be the only entity allowed to issue money in Switzerland. This was followed two years later by the first Federal Coinage Act, passed by the Federal Assembly on 7 May 1850, which introduced

11772-472: Was the invention of a British watch repairer named John Harwood in 1923. This type of watch winds itself without requiring any special action by the wearer. It uses an eccentric weight, called a winding rotor, which rotates with the movement of the wearer's wrist. The back-and-forth motion of the winding rotor couples to a ratchet to wind the mainspring automatically. Self-winding watches usually can also be wound manually to keep them running when not worn or if

11881-467: Was valued at 2 + 18 ⁄ 40 gulden; see Zürich thaler and Schwyz gulden . On the other hand, the central Swiss cantons of Luzern, Uri, Zug and Unterwalden maintained a weaker gulden vs the South German gulden . The French écu was valued at 3 gulden, while the kronenthaler was valued at 2 + 37 ⁄ 40 gulden (see Luzern gulden ). In 1798, the Helvetic Republic introduced
