Watch - Time piece - Fashion Wear
A watch is a small, portable timepiece, especially one worn on the wrist or carried in the pocket. A wristwatch is fastened to the wrist with a strap or bracelet. A pocket watch is typically a watch on a chain, intended to be carried in the pocket of a jacket or vest. Watches track and display the passage of time or "the time" (meaning hours, minutes and (sometimes) seconds), though a wide range of watches are capable of displaying calendar day, day of week, year or sub-second units like 1/10 or 1/100 of a second. Watches that provide additional time-related features such as timers, chronographs and alarm functions are not uncommon. Some modern designs even go as far as using GPS technology or heart-rate monitoring capabilities.
Before wristwatches became popular in the 1920s, most watches were pocket watches, which often had covers and were carried in a pocket and attached to a watch chain or watch fob. Watches evolved in the 17th century from spring powered clocks, which appeared in the 15th century.
In early 1900's, the wristwatch, originally called a Wristlet, was reserved for women and considered more of a passing fad than a serious timepiece. Real gentlemen, who carried pocket watches, were actually quoted as saying they would "sooner wear a skirt as wear a wristwatch". This all changed in World War I when soldiers on the battlefield found using a pocket watch to be impractical, so they attached the pocket watch to their wrist by a cupped leather strap. It is also believed that Girard-Perregaux equipped the German Imperial Navy in a similar fashion as early as the 1880's, which were used while synchronizing naval attacks and firing artillery.
The first watches were strictly mechanical. As technology progressed, the mechanisms used to measure time has in some cases been replaced by use of quartz vibrations or electromagnetic pulses and is called a quartz movements. Watches vary as wildly in their different designs as they do in prices, ranging from a few dollars to well into the millions. Designer fashion watch manufacturers often have purely mechanical movements and are powered by springs, even though mechanical movements are less accurate than more affordable quartz movements. Collectible watches are driven up in value by collectors for more than just their timekeeping ability; due to meticulous workmanship, aesthetic appeal and limited production, some of these pieces have sold for more than 10 million ($10,000,000) USD.
The first digital electronic watch, a Pulsar LED prototype in 1970, was developed jointly by Hamilton Watch Company and Electro-Data. John Bergey, the head of Hamilton's Pulsar division, said that he was inspired to make a digital timepiece by the then-futuristic digital clock that Hamilton themselves made for the 1968 science fiction film 2001: A Space Odyssey. On April 4, 1972, the Pulsar was finally ready, made in 18-carat gold and sold for $2,100. It had a red light-emitting diode (LED) display. (wikipedia)
