Rolex SA (ˈroʊlɛks) is a Swiss watch designer and manufacturer based in Geneva, Switzerland. Founded in 1905 as Wilsdorf and Davis by Hans Wilsdorf and Alfred Davis in London, the company registered Rolex as the brand name of its watches in 1908 and became Rolex Watch Co. Ltd. in 1915. After World War I, the company moved its base of operations to Geneva because of the unfavorable economy in the United Kingdom. In 1920, Hans Wilsdorf registered Montres Rolex SA in Geneva as the new company name (montre is French for clock or watch); it later became Rolex SA. Since 1960, the company has been owned by the Hans Wilsdorf Foundation, a private family trust.
Rolex SA and its subsidiary Montres Tudor SA design, make, distribute, and service wristwatches sold under the Rolex and Tudor brands.
Alfred Davis and his brother-in-law Hans Wilsdorf founded Wilsdorf and Davis, the company that would eventually become Rolex SA, in London in 1905. Wilsdorf and Davis's main commercial activity at the time involved importing Hermann Aegler's Swiss movements to England and placing them in watch cases made by Dennison and others. These early wristwatches were sold to many jewellers, who then put their own names on the dial. The earliest watches from Wilsdorf and Davis were usually hallmarked "W&D" inside the caseback.
In 1908, Wilsdorf registered the trademark "Rolex", which became the brand name of watches from Wilsdorf and Davis. He opened an office in La Chaux-de-Fonds, Switzerland. Wilsdorf wanted the brand name to be easily pronounceable in any language, and short enough to fit on the face of a watch. He also thought that the name "Rolex" was onomatopoeic, sounding like a watch being wound.
During the First world war, Rolex manufactured trench watches. In November 1915, the company changed its name to Rolex Watch Co. Ltd. In 1919, Hans Wilsdorf moved the company from England to Geneva, Switzerland, because of heavy post-war taxes levied on luxury imports and high export duties on the silver and gold used for the watch cases.

Since the invention of the pendulum clock by Christiaan Huygens in 1657, precision timekeepers have been regulated by oscillators. Although the pendulum is not an isochronous oscillator, its introduction as a time basis for clock regulation led to a signif ...
, commonly known as Seiko (ˈseɪkoʊ , seːkoː), is a Japanese maker of watches, clocks, electronic devices, semiconductors, jewelry, and optical products. Founded in 1881 by Kintarō Hattori in Tokyo, Seiko introduced the world's first commercial quartz wristwatch in 1969. Seiko is perhaps best known for its wristwatches. Along with Rolex, Seiko is one of only two watch companies considered to be vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house.
A chronometer (χρονόμετρον, khronómetron, "time measurer") is an extraordinarily accurate mechanical timepiece, with an original focus on the needs of maritime navigation. In Switzerland, timepieces certified by the Contrôle Officiel Suisse des Chronomètres (COSC) may be marked as Certified Chronometer or Officially Certified Chronometer. Outside Switzerland, equivalent bodies, such as the Japan Chronometer Inspection Institute, have in the past certified timepieces to similar standards, although use of the term has not always been strictly controlled.
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. 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 Seiko, Citizen, and Casio which embraced the new electronic technology.
In vitro estrogen receptor transactivation assays (ERTAs) are increasingly used to measure the overall estrogenic activity of environmental water samples, which may serve as an indicator of exposure of fish or other aquatic organisms to (xeno)estrogens. An ...
Geothermometrical characterisation of low-temperature, carbonate-evaporitic geothermal systems is usually hampered by the lack of appropriate mineral equilibria to successfully use most of the classical geothermometers and/or by the thermodynamic uncertain ...
