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.
Horology is the study of the measurement of time. Clocks, watches, clockwork, sundials, hourglasses, clepsydras, timers, time recorders, marine chronometers, and atomic clocks are all examples of instruments used to measure time. In current usage, horology refers mainly to the study of mechanical time-keeping devices, while chronometry more broadly includes electronic devices that have largely supplanted mechanical clocks for the best accuracy and precision in time-keeping.
The Worshipful Company of Clockmakers was established under a royal charter granted by King Charles I in 1631. It ranks sixty-first among the livery companies of the City of London, and comes under the jurisdiction of the Privy Council. The company established a library and its museum in 1813, which is the oldest specific collection of clocks and watches worldwide. This is administered by the company's affiliated charity, the Clockmakers' Charity, and is presently housed on the second floor of London's Science Museum. The modern aims of the company and its museum are charitable and educational, in particular to promote and preserve clockmaking and watchmaking, which as of 2019 were added to the HCA Red List of Endangered Crafts.
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 mainspring is a spiral torsion spring of metal ribbon—commonly spring steel—used as a power source in mechanical watches, some clocks, and other clockwork mechanisms. Winding the timepiece, by turning a knob or key, stores energy in the mainspring by twisting the spiral tighter. The force of the mainspring then turns the clock's wheels as it unwinds, until the next winding is needed. The adjectives wind-up and spring-powered refer to mechanisms powered by mainsprings, which also include kitchen timers, metronomes, music boxes, wind-up toys and clockwork radios.
A fusee is a cone-shaped pulley with a helical groove around it, wound with a cord or chain attached to the mainspring barrel of antique mechanical watches and clocks. It was used from the 15th century to the early 20th century to improve timekeeping by equalizing the uneven pull of the mainspring as it ran down. Gawaine Baillie stated of the fusee, "Perhaps no problem in mechanics has ever been solved so simply and so perfectly."
A lantern clock is a type of antique weight-driven wall clock, shaped like a lantern. They were the first type of clock widely used in private homes. They probably originated before 1500 but only became common after 1600; in Britain around 1620. They became obsolete in the 19th century.
The Clockmakers’ Museum in London, England, is believed to be the oldest collection specifically of clocks and watches in the world. The collection belongs to and is administered by the Clockmakers’ Charity, affiliated to the Worshipful Company of Clockmakers, founded in 1631 by Royal Charter. Since 2015 it has been housed in a gallery provided by the Science Museum in South Kensington, having formerly been located in the Guildhall complex in the City of London since 1874, where it first opened to the public. Admission is free.
Thomas Tompion, FRS (1639–1713) was an English clockmaker, watchmaker and mechanician who is still regarded to this day as the "Father of English Clockmaking". Tompion's work includes some of the most historic and important clocks and watches in the world, and can command very high prices whenever outstanding examples appear at auction. A plaque commemorates the house he shared on Fleet Street in London with his equally famous pupil and successor George Graham.
George Daniels, CBE, FBHI, FSA, AHCI was an English horologist who was considered by some to be one of the best in the world in the field of luxury mechanical watches and timepieces during his lifetime. He was a watchmaker who built complete watches by hand. But it was his creation of the coaxial escapement for which he is most remembered. The movement, which theoretically removed the need to add a lubricant, has been used by Omega in most of their collections since 1999 with the exception of the Speedmaster Moonwatch.
The American Watchmakers-Clockmakers Institute (AWCI) is a not-for-profit trade association based in the United States that is dedicated to the advancement of the modern watch industry, from which it receives a significant portion of its funding. While the AWCI is an American organization, it also has members throughout the world.
The German Clock Museum is situated near the centre of the Black Forest town of Furtwangen im Schwarzwald (Germany), a historical centre of clockmaking. It features permanent and temporary exhibits on the history of timekeeping. The museum is part of the local technical college.
The British Horological Institute (BHI) is the representative body of the horological industry in the United Kingdom. It was founded by a group of clockmakers in 1858, and has its current premises at Upton Hall in Nottinghamshire, which includes a museum of clock history.
The Antiquarian Horological Society, abbreviated to AHS, is the UK-based learned society for scholars and enthusiasts of horology. Its administrative office is at 4 Lovat Lane, a listed building close to the Monument, in the City of London. In early 2016, the Society appointed Dr Patricia Fara of Clare College, Cambridge as its new president, following the untimely death of its previous president Professor Lisa Jardine. The Chairman is Dr James Nye.
Daniel Quare was an English clockmaker and instrument maker who invented a repeating watch movement in 1680 and a portable barometer in 1695.
Benjamin Vulliamy, was a British clockmaker responsible for building the Regulator Clock, which, between 1780 and 1884, was the main timekeeper of the King's Observatory Kew and the official regulator of time in London. In 1773 Vulliamy had received a Royal Appointment as the King's Clockmaker.
Jean-Antoine Lépine, born as Jean-Antoine Depigny, was an influential watchmaker. He contributed inventions which are still used in watchmaking today and was amongst the finest French watchmakers, who were contemporary world leaders in the field.
Joseph Windmills (c1640-1724), was an eminent London watch- and clockmaker who, with his son Thomas, produced outstanding timepieces between 1671 and 1737.
Charles Gretton was an English clock and watchmaker during the golden age of English clockmaking.
