Most Gallet Clamshell chronographs measure 34.2 millimeters in diameter (not measuring the winding crown) by approximately 42 millimeters in overall length, with a few smaller and larger examples released during the 1940s. The Clamshell's 15-year history began in 1936 when Gallet purchased the rights to a patent for the "waterproof" watch case design (Brevet N° 189190), invented by the Swiss firm of Schmitz Frèr ...

Chronograph
A chronograph is a specific type of watch that is used as a stopwatch combined with a display watch. A basic chronograph has an independent sweep second hand and a minute sub-dial; it can be started, stopped, and returned to zero by successive pressure on the stem. More complex chronographs use additional Complication (horology), complications and can have multiple sub-dials to measure seconds, minutes, hours and even fractions of a second. In addition, many modern chronographs use moveable bezels as Tachymeter (watch), tachymeters for rapid calculations of speed or distance. Louis Moinet invented the chronograph in 1816 for use in tracking astronomical objects. Chronographs were also used heavily in artillery fire in the mid to late 1800s. More modern uses of chronographs involve aircraft piloting, auto racing, Underwater diving, diving and submarine maneuvering. Since the 1980s, the term ''chronograph'' has also been applied to all Watch#Digital, digital watches that incorpor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eaton's
The T. Eaton Company Limited, later known as Eaton's, was a Canadian department store chain that was once the largest in the country. It was founded in 1869 in Toronto by Timothy Eaton, an immigrant from what is now Northern Ireland. Eaton's grew to become a retail and social institution in Canada, with stores across the country, buying-offices around the globe, and a mail-order catalog that was found in the homes of most Canadians. A changing economic and retail environment in the late twentieth century, along with mismanagement, culminated in the chain's bankruptcy in 1999. Eaton's pioneered several retail innovations. In an era when haggling for goods was the norm, the chain proclaimed "We propose to sell our goods for CASH ONLY – In selling goods, to have only one price." In addition, it had the long-standing slogan "Goods Satisfactory or Money Refunded." Early years In 1869, Timothy Eaton sold his interest in a small dry-goods store in the market town of St. Marys, Ontari ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tachymeter (watch)
A tachymeter (pronounced ) is a scale sometimes inscribed around the rim of an analog watch with a chronograph. It can be used to conveniently compute the frequency in hours of an event of a known second-defined period, such as speed (distance over hours) based on travel time (distance over speed), or measure distance based on speed. The spacings between the marks on the tachymeter dial are therefore proportional to , where ''t'' is the elapsed time. The function performed by a tachymeter is independent of the unit of distance (e.g. statute miles, nautical miles, kilometres, metres etc.) as long as the same unit of length is used for all calculations. It can also be used to measure the frequency of any regular event in occurrences per hour, such as the units output by an industrial process. A tachymeter is simply a means of converting ''elapsed time'' (in seconds per unit) to ''rate'' (in units per hour). Measuring speed To use a tachymeter-equipped watch for measuring speed, ...

Radium
Radium is a chemical element with the symbol Ra and atomic number 88. It is the sixth element in group 2 of the periodic table, also known as the alkaline earth metals. Pure radium is silvery-white, but it readily reacts with nitrogen (rather than oxygen) upon exposure to air, forming a black surface layer of radium nitride (Ra3N2). All isotopes of radium are radioactive, the most stable isotope being radium-226 with a half-life of 1600 years. When radium decays, it emits ionizing radiation as a by-product, which can excite fluorescent chemicals and cause radioluminescence. Radium, in the form of radium chloride, was discovered by Marie and Pierre Curie in 1898 from ore mined at Jáchymov. They extracted the radium compound from uraninite and published the discovery at the French Academy of Sciences five days later. Radium was isolated in its metallic state by Marie Curie and André-Louis Debierne through the electrolysis of radium chloride in 1911. In nature, radium is found ...
