Ă©bauche
(loanword from French, meaning blank, outline or sketch) is a term used in art to denote the first preliminary underpainting or quick sketch in oils for an oil painting. Horology, clockmaking and watchmaking appropriated the term ébauche to refer to an incomplete or unassembled watch movement and its associated components. The French term is regularly used by English-speaking artists and art historians, as well as horologists and hobbyists. Art One early criticism of Impressionist painting was that its practitioners sought to elevate the status of the ébauche to the level of finished painting. Horology Until about 1850, the watchmaker’s ébauche consisted of two plates with pillars and bars, the barrel, fusée, index, pawl and ratchet-wheel, along with a few assembling screws. These parts were all roughly filed and milled. The steel and brass were manufactured in a special workshop. The ébauche was finished by watchmakers in a finishing shop. The (literally "assort ...

ETA SA
ETA SA Manufacture Horlogère Suisse (ETA SA Swiss Watch Manufacturer) designs and manufactures quartz watches and both hand-wound and automatic-winding mechanical and movements. Commonly referred to as ETA, the company is headquartered in Grenchen, Switzerland, and is a wholly owned subsidiary of The Swatch Group. Though ETA was founded by Eterna in 1856 some part of its production line can be traced back to the 1793 founding of Fabriques d’Horlogerie de Fontainemelon (FHF) by David Benguerel, Isaac Benguerel, François Humbert-Droz and Julien Humbert-Droz. Through a series of mergers, ETA has become the largest manufacturer of Swiss watch movements and controls a virtual monopoly over their production and supply. ETA has undergone several Swiss government investigations due to its market position. To resolve the concerns of Swiss government regulators, ETA has entered into an agreement that governs certain business practices. Description ETA designs and manufactures mecha ...

Horology
Horology (; related to Latin '; ; , interfix ''-o-'', and suffix ''-logy''), . 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. People interested in horology are called ''horologists''. That term is used both by people who deal professionally with timekeeping apparatuses (watchmakers, clockmakers), as well as aficionados and scholars of horology. Horology and horologists have numerous organizations, both professional associations and more scholarly societies. The largest horological membership organisation globally is the NAWCC, the National Association of Wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Movement (clockwork)
In horology, a movement, also known as a caliber or calibre (British English), is the mechanism of a watch or Clock, timepiece, as opposed to the ''case'', which encloses and protects the movement, and the ''clock face, 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. In modern mass-produced clocks and watches, the same movement is often inserted into many different styles of case. When buying a quality pocketwatch from the mid-19th to the mid-20th century, for example, the customer would select a movement and case individually. Mechanical movements get dirty and the lubricants dry up, so they must periodically be disassembled, cleaned, and lubricated. One source recommends servicing intervals of: 3–5 years for watches, 15–20 years for grandfather clocks, 10–15 years for wall or mantel clocks, 15–20 years for anniv ...

Valjoux
Valjoux (for ''Vallée de Joux'', "Joux Valley") is a Swiss Made, Swiss manufacturer of mechanical watch movement (clockwork), movements. It is known primarily for chronograph ébauche movements that are used in a number of mid- to high-range mechanical watches. The company is a part of ETA SA, ETA, and is a member of the Swatch Group. They are also the movement providers for early Rolex Daytonas such as 6263. Valjoux 7750 Valjoux is responsible for the design and manufacture of the Valjoux 7750 movement (and variants), an extremely popular movement used in many mechanical watch, mechanical chronograph watches. The Valjoux 7750 is different from most other chronograph movements, using the three-plane cam system rather than the column wheel. It is constructed of a mainplate, calendar plate, and chronograph top plate. Levers push a cam back and forth, driving the stopwatch mechanism of the Valjoux 7750. This is referred to as a ''coulisse''-lever escapement. In the 1980s, many co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Loanword
A loanword (also loan word or loan-word) is a word at least partly assimilated from one language (the donor language) into another language. This is in contrast to cognates, which are words in two or more languages that are similar because they share an etymological origin, and calques, which involve translation. Loanwords from languages with different scripts are usually transliterated (between scripts), but they are not translated. Additionally, loanwords may be adapted to phonology, phonotactics, orthography, and morphology of the target language. When a loanword is fully adapted to the rules of the target language, it is distinguished from native words of the target language only by its origin. However, often the adaptation is incomplete, so loanwords may conserve specific features distinguishing them from native words of the target language: loaned phonemes and sound combinations, partial or total conserving of the original spelling, foreign plural or case forms or indecli ...

Brass
Brass is an alloy of copper (Cu) and zinc (Zn), in proportions which can be varied to achieve different mechanical, electrical, and chemical properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure. Brass is similar to bronze, another copper alloy, that uses tin instead of zinc. Both bronze and brass may include small proportions of a range of other elements including arsenic (As), lead (Pb), phosphorus (P), aluminium (Al), manganese (Mn), and silicon (Si). Historically, the distinction between the two alloys has been less consistent and clear, and modern practice in museums and archaeology increasingly avoids both terms for historical objects in favor of the more general "copper alloy". Brass has long been a popular material for decoration due to its bright, gold-like appearance; being used for drawer pulls and doorknobs. It has also been widely used to make utensils because of its low melting ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Swatch Group Ltd
The Swatch Group Ltd is a Swiss manufacturer of watches and jewellery. The company was founded in 1983 by the merger of ASUAG and SSIH to move to manufacturing quartz-crystal watches to resolve the quartz crisis threatening the traditional Swiss watchmaking industry. The Swatch Group is the world's largest watch company and employs about 36,000 people in 50 countries. The group owns the Swatch product line and other brands, including Blancpain, Breguet, Certina, ETA, Glashütte Original, Hamilton, Harry Winston, Longines, Mido, Omega, Rado, and Tissot. History SSIH SSIH (Société Suisse pour l'Industrie Horlogère), originated in 1930 with the merger of the Omega and Tissot companies. Swiss watch quality was high, but new technology, such as the Hamilton Electric watch introduced in 1957 and the Bulova Accutron tuning fork watch in 1961, presaged increasing technological competition. In the late 1970s, SSIH became insolvent due in part to a recession and in part to heav ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quartz Crisis
The quartz crisis was the upheaval in the watchmaking industry caused by the advent of quartz watches in the 1970s and early 1980s, that largely replaced mechanical watches around the world.Smithsonian: The quartz revolution revitalized the U.S. watch industry. It caused a significant decline of the Swiss watchmaking industry, which chose to remain focused on traditional mechanical watches, while the majority of the world's watch production shifted to Japanese companies such as , [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Waltham Watch Company
The Waltham Watch Company, also known as the American Waltham Watch Co. and the American Watch Co., was a company that produced about 40 million watches, clocks, speedometers, compasses, time delay fuses, and other precision instruments in the United States of America between 1850 and 1957. The company's historic 19th-century manufacturing facilities in Waltham, Massachusetts have been preserved as the American Waltham Watch Company Historic District. The company went through a series of bankruptcies and restarts under new ownership, with watches and clocks bearing the Waltham name still being made and marketed today. History The early years, 1849 to 1857 Prior to 1850, watches in America were generally supplied either from England or Switzerland.Caross, "The Waltham Watch Co.," p. 167. The idea for the Waltham Watch Company came from watchmaker Aaron Lufkin Dennison. Dennison was the son of a shoemaker, born in Maine in 1812.Caross, "The Waltham Watch Co.," p. 166. He ser ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...
