A watch is a small timepiece intended to be carried or worn by a person. It is designed to keep working despite the motions caused by the person’s activities. A wristwatch is designed to be worn on a wrist, attached by a watch strap or other type of bracelet. A pocket watch is designed for a person to carry in a pocket.

Watches evolved 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, powered by winding a mainspring which turned gears and then moved the hands, and kept time with a rotating balance wheel. In the 1960s the electronic quartz watch was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from the mechanical watch.

The first timepieces to be worn, made in the 16th century beginning in Germany, were transitional in size between clocks and watches. These ‘clock-watches’ were fastened to clothing or worn on a chain around the neck. They were heavy drum shaped brass cylinders several inches in diameter, engraved and ornamented. They had only an hour hand. The face was not covered with glass, but usually had a hinged brass cover, often decoratively pierced with grillwork so the time could be read without opening. The movement was made of iron or steel and held together with tapered pins and wedges, until screws began to be used after 1550. Many of these watches were signed by their makers.
