watcheswatcheswatches:A watch is a small timepiece
A  watch is a small timepiece, typically worn either on the wrist or  attached on a chain and carried in a pocket, with wristwatches being the  most common type of watch used today. They evolved in the 17th century  from spring powered clocks, which appeared in the 15th century. The  first watches were strictly mechanical.

As  technology progressed, the mechanisms used to measure time have, in  some cases, been replaced by use of quartz vibrations or electromagnetic  pulses and are called quartz movements.The first digital electronic  watch was developed in 1970.

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.In early 1900s, 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 1880s, which were used while  synchronizing naval attacks and firing artillery.
Most  inexpensive and medium-priced watches used mainly for timekeeping are  electronic watches with quartz movements.Expensive, collectible watches  valued more for their workmanship and aesthetic appeal than for simple  timekeeping, often have purely mechanical movements and are powered by  springs, even though mechanical movements are less accurate than more  affordable quartz movements.
In  addition to the time, modern watches often display the day, date, month  and year, and electronic watches may have many other functions. 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.
