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.

The first timepieces to be worn, made in the 16th century beginning in the German cities of Nuremberg and Augsburg , were transitional in size between clocks and watches. Watches were not widely worn in pockets until the 17th century. One account suggests that the word "watch" came from the Old English word woecce — which meant "watchman" — because town watchmen used the technology to keep track of their shifts at work. A rise in accuracy occurred in with the addition of the balance spring to the balance wheel, an invention disputed both at the time and ever since between Robert Hooke and Christiaan Huygens.
