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 is designed for a person to carry in a pocket, often attached to a chain. A stopwatch is a watch that measures intervals of time.
Abraham-Louis Breguet, born in Neuchâtel, then a Prussian principality, was a horologist who made many innovations in the course of a career in watchmaking industry, including the tourbillon. He was the founder of the Breguet company, which is now a luxury watch division of the Swiss Swatch Group.
A watchmaker is an artisan who makes and repairs watches. Since a majority of watches are now factory-made, most modern watchmakers only repair watches. However, originally they were master craftsmen who built watches, including all their parts, by hand. Modern watchmakers, when required to repair older watches, for which replacement parts may not be available, must have fabrication skills, and can typically manufacture replacements for many of the parts found in a watch. The term clockmaker refers to an equivalent occupation specializing in clocks.
A clockmaker is an artisan who makes and/or repairs clocks. Since almost all clocks are now factory-made, most modern clockmakers only repair clocks. Modern clockmakers may be employed by jewellers, antique shops, and places devoted strictly to repairing clocks and watches. Clockmakers must be able to read blueprints and instructions for numerous types of clocks and time pieces that vary from antique clocks to modern time pieces in order to fix and make clocks or watches. The trade requires fine motor coordination as clockmakers must frequently work on devices with small gears and fine machinery.
A pocket watch is a watch that is made to be carried in a pocket, as opposed to a wristwatch, which is strapped to the wrist.
In horology, a movement, also known as a caliber or calibre, is the mechanism of a watch or timepiece, as opposed to the case, which encloses and protects the movement, and the face, which displays the time. The term originated with mechanical timepieces, whose clockwork movements are made of many moving parts. The movement of a digital watch is more commonly known as a module.
Patek Philippe SA is a Swiss luxury watch and clock manufacturer, located in the Canton of Geneva and the Vallée de Joux. Established in 1839, it is named after two of its founders, Antoni Patek and Adrien Philippe. Since 1932, the company has been owned by the Stern family in Switzerland and remains the last family-owned independent watch manufacturer in Geneva. Patek Philippe is one of the oldest watch manufacturers in the world with an uninterrupted watchmaking history since its founding. It designs and manufactures timepieces as well as movements, including some of the most complicated mechanical watches. The company maintains over 400 retail locations globally and over a dozen distribution centers across Asia, Europe, North America, and Oceania. In 2001, it opened the Patek Philippe Museum in Geneva.
In horology, a tourbillion or tourbillon is an addition to the mechanics of a watch escapement to increase accuracy. Conceived by the British watchmaker and inventor John Arnold, it was developed by his friend the Swiss-French watchmaker Abraham-Louis Breguet and patented by Breguet on 26 June 1801. In a tourbillon, the escapement and balance wheel are mounted in a rotating cage, with the goal of eliminating errors of poise in the balance giving a uniform weight.
In horology, a complication is any feature of a timepiece beyond the display of hours, minutes and seconds. A timepiece indicating only hours, minutes and seconds is known as a simple movement. Common complications include date or day-of-the-week indicators, alarms, chronographs (stopwatches), and automatic winding mechanisms. Complications may be found in any clock, but they are most notable in mechanical watches where the small size makes them difficult to design and assemble. A typical date-display chronograph may have up to 250 parts, while a particularly complex watch may have a thousand or more parts. Watches with several complications are referred to as grandes complications.
John Arnold was an English watchmaker and inventor.
Chronometry or horology is the science studying the measurement of time and timekeeping. Chronometry enables the establishment of standard measurements of time, which have applications in a broad range of social and scientific areas. Horology usually refers specifically to the study of mechanical timekeeping devices, while chronometry is broader in scope, also including biological behaviours with respect to time (biochronometry), as well as the dating of geological material (geochronometry).
The International Museum of Horology, French: Musée international d'horlogerie, is a horological museum in La Chaux-de-Fonds, Switzerland. It is owned and operated by the city of La Chaux-de-Fonds.
The National Watch and Clock Museum (NWCM), located in Columbia, Pennsylvania, is one of a very few museums in the United States dedicated solely to horology, which is the history, science and art of timekeeping and timekeepers.
A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch is driven by a mainspring which must be wound either periodically by hand or via a self-winding mechanism. Its force is transmitted through a series of gears to power the balance wheel, a weighted wheel which oscillates back and forth at a constant rate. A device called an escapement releases the watch's wheels to move forward a small amount with each swing of the balance wheel, moving the watch's hands forward at a constant rate. The escapement is what makes the 'ticking' sound which is heard in an operating mechanical watch. Mechanical watches evolved in Europe in the 17th century from spring powered clocks, which appeared in the 15th century.
The Watch Museum of Le Locle is a municipal museum specializing in horology, located in Le Locle, Canton of Neuchâtel, Switzerland. It is open to the public.
Gallet (ˈgæl.eɪ) is a historic Swiss manufacturer of high-end timepieces for professional, military, sports, racing, and aviation use. Gallet is the world's oldest clock making house with history dating back to Humbertus Gallet, a clock maker who became a citizen of Geneva in 1466. It is one of the oldest continuously operating companies in the World. The Gallet & Cie name was officially registered by Julien Gallet (1806–1849) in 1826, who moved the family business from Geneva to La Chaux-de-Fonds, Switzerland. Prior to this date, operations commenced under the name of each of the Gallet family patriarchs.
Jean Lassale was a Swiss watch company that designed the Calibre 1200, featuring the thinnest mechanical watch movement: 1.2 mm. In the 1970s, Pierre Mathys, master watchmaker in La Chaux-de-Fonds, designed and built the prototype of a revolutionary watch caliber, with the goal of making the thinnest watch in the world. To achieve this feat, Mathys based his design on the work of Robert Annen, who previously had the idea of using ball bearings in small scale horology. Mathys decided to remove the bridges and counter-pivot, and instead use ball bearings for the axis.
Dominique Loiseau was a French and Swiss watchmaker who worked at the highest levels of complex horology from the mid 1970s onwards He was the creator of several notable timepieces, including six Montres de Sables, the Rose de Temps clock, the Renaissance or Capriccio pocket watches and the Blancpain 1735 wristwatch. In 2011 he presented, the Loiseau 1f4, one of the most complicated automatic watches with eight patents. Loiseau announced in 2012 a collaboration with Swiss watch manufacturer Girard-Perregaux.
Charles Oudin is one of the oldest French horology firms. It was founded in Paris at the end of the 18th century by Jean-Charles Oudin, who came from a family of clockmakers in Northwest France. There were four generations of Oudins who were clockmakers, as of the mid 18th century, first in the Meuse region and later, in Paris. Several members of the Oudin family worked for the master watch and clockmaker Abraham-Louis Breguet.
Konstantin Chaykin is a Russian watchmaker and inventor. He started as an independent watchmaker in 2003, establishing a workshop in St. Petersburg, Russia. In the interests of the business, in 2012 he transferred production to Moscow, Russia, where his company currently resides. He completed his first clock in 2004. and in 2008 Académie Horlogère des Créateurs Indépendants accepted him as a candidate. Since 2010 he has been a member of the AHCI, while in 2016 he was elected by AHCI members as the President, a position held until 2019. In October 2022, the jury of the Temporis International Awards included Konstantin Chaikin in the Temporis Hall of Fame.
