Deutsche Gesellschaft Für Chronometrie
Deutsche Gesellschaft für Chronometrie (DGC), (German Society for Timekeeping) today is an organization of scholars, collectors and enthusiasts in Germany interested in the science, art and history of horology. History The association was founded in the post World War II years (as an unofficial successor to the ') and originally consisted mainly of scientists and engineers from the watch and clock producing industry. Over the years more people joined who were interested in the history of timekeeping devices, and eventually two separate divisions were set up, a ' (Scientific Division) and a ' (Historical Division). When the clock and watch industry withered in the fourth quarter of the 20th century the technical division withered, and by 2000 the divisional structure was dropped. Today the bulk of the membership unites collectors, scholars and museum professionals interested in the historical aspects of clocks, sundials and watches.

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] |
Clock
A clock or a timepiece is a device used to measure and indicate time. The clock is one of the oldest human inventions, meeting the need to measure intervals of time shorter than the natural units such as the day, the lunar month and the year. Devices operating on several physical processes have been used over the millennia. Some predecessors to the modern clock may be considered as "clocks" that are based on movement in nature: A sundial shows the time by displaying the position of a shadow on a flat surface. There is a range of duration timers, a well-known example being the hourglass. Water clocks, along with the sundials, are possibly the oldest time-measuring instruments. A major advance occurred with the invention of the verge escapement, which made possible the first mechanical clocks around 1300 in Europe, which kept time with oscillating timekeepers like balance wheels., pp. 103–104., p. 31. Traditionally, in horology, the term ''clock'' was used for a stri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sundial
A sundial is a horological device that tells the time of day (referred to as civil time in modern usage) when direct sunlight shines by the apparent position of the Sun in the sky. In the narrowest sense of the word, it consists of a flat plate (the ''dial'') and a gnomon, which casts a shadow onto the dial. As the Sun appears to move through the sky, the shadow aligns with different hour-lines, which are marked on the dial to indicate the time of day. The ''style'' is the time-telling edge of the gnomon, though a single point or ''nodus'' may be used. The gnomon casts a broad shadow; the shadow of the style shows the time. The gnomon may be a rod, wire, or elaborately decorated metal casting. The style must be parallel to the axis of the Earth's rotation for the sundial to be accurate throughout the year. The style's angle from horizontal is equal to the sundial's geographical latitude. The term ''sundial'' can refer to any device that uses the Sun's altitude or azimut ...

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 is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th 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 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 mechani ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pocket Watch
A pocket watch (or pocketwatch) is a watch that is made to be carried in a pocket, as opposed to a watch, wristwatch, which is strapped to the wrist. They were the most common type of watch from their development in the 16th century until wristwatches became popular after World War I during which a transitional design, trench watches, were used by the military. Pocket watches generally have an attached chain to allow them to be secured to a waistcoat, lapel, or belt (clothing), belt loop, and to prevent them from being dropped. Watches were also mounted on a short leather strap or fob, when a long chain would have been cumbersome or likely to catch on things. This fob could also provide a protective flap over their face and crystal. Women's watches were normally of this form, with a watch fob that was more decorative than protective. Chains were frequently decorated with a silver or Vitreous enamel, enamel pendant, often carrying the arms of some Club (organization), club or s ...

Tower Clock
Clock towers are a specific type of structure which house a turret clock and have one or more clock faces on the upper exterior walls. Many clock towers are freestanding structures but they can also adjoin or be located on top of another building. Some other buildings also have clock faces on their exterior but these structures serve other main functions. Clock towers are a common sight in many parts of the world with some being iconic buildings. One example is the Elizabeth Tower in London (usually called " Big Ben", although strictly this name belongs only to the bell inside the tower). Definition There are many structures which may have clocks or clock faces attached to them and some structures have had clocks added to an existing structure. According to the Council on Tall Buildings and Urban Habitat a structure is defined as a building if at least fifty percent of its height is made up of floor plates containing habitable floor area. Structures that do not meet this c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Facsimile
A facsimile (from Latin ''fac simile'', "to make alike") is a copy or reproduction of an old book, manuscript, map, Old master print, art print, or other item of historical value that is as true to the original source as possible. It differs from other forms of reproduction by attempting to replicate the source as accurately as possible in scale, color, condition, and other material qualities. For books and manuscripts, this also entails a complete copy of all pages; hence, an incomplete copy is a "partial facsimile". Facsimiles are sometimes used by scholars to research a source that they do not have access to otherwise, and by museums and archives for media preservation and Art conservation and restoration, conservation. Many are sold commercially, often accompanied by a volume of commentary. They may be produced in limited editions, typically of 500–2,000 copies, and cost the equivalent of a few thousand United States dollars. The term "fax" is a shortened form of "facsimile" ...

Chronometrophilia
Chronometrophilia is described in its byline as the "Swiss Association for the History of Timekeeping / Association suisse pour l'histoire de la mesure du temps / Schweizerische Gesellschaft für die Geschichte der Zeitmessung". It is a group of collectors and enthusiasts interested in the history of horology. Given that Switzerland is quadrilingual, they needed a language-neutral name for their organisation. They invented the term ''chronometrophilia'' from the Greek ''chronos'' (time) and ''philia'' ("the love of"); and ''meter'', a Teutonic word cognate to the Latin ''modius'' (bushel).Oxford English Dictionary. (1989) 2nd Ed. The association was founded in 1976 and unites collectors, scholars and museum professionals interested in the historical aspects of clocks and watches. Meetings are held about 4 times a year in various locations in Switzerland and are usually conducted bilingually in French and German. Most meetings involve visits to museums, restoration workshops or p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Association Of Watch And Clock Collectors
The National Association of Watch & Clock Collectors, Inc. (NAWCC) is a nonprofit association of people who share a passion for collecting watches and clocks and studying horology (the art and science of time and timekeeping). The NAWCC's global membership is composed of nearly 10,000 individuals, businesses, and institutions, with more than 1.25 million users accessing its main website and online Forums each year. The Forums, offer NAWCC members and nonmembers the opportunity to ask questions about watches and clocks. The NAWCC was founded in 1943 by members of the ''Horological Society of New York'' and the ''Philadelphia Watchmakers' Guild'' who wished to create a national organization focused on providing education and advocacy for horology. Many of the members participate in one or more of the 145 "Chapters" that are based on a locality or a special interest (e.g., the local chapter for New York is ''Chapter 2'' and the ''Tower Clock Chapter'' is ''Chapter 134'').
