Watch (timepiece)

A watch is a small portable clock which displays the current time. Until the advent of digital (quartz) watches, only purely mechanical timepieces were used. There are wrist watches and pocket watches. Watches may be collectible; they are often made of precious metals, and can be considered an article of jewelry.

Prominent makers of mechanical watches include:

• Breguet
• Rolex
• Orient
• Seiko

Prominent makers of digital watches include:

• Timex
• Casio

The science of timekeeping, clocks and watches is horology.
