A watch is a timepiece that is made to be worn on a person, as different to a clock which is not. The term now generally refers to a wristwatch, which is worn on the wrist with a strap or bracelet. In addition to the time, modern watches often display the day, date, month and year, and electronic watches may have many other facilities.

Most low-cost and medium-priced watches used mainly for timekeeping are electronic watches with quartz movements. Luxurious, 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.

Before the low-cost miniaturization that became possible in the 20th century, most watches were pocket watches, which had covers and were carried in a pocket and attached to a watch chain or watch fob. Watches evolved in the 1600s from spring
power-driven clocks, which appeared in the 1400s.
