Description

The Wrist Watch is a manufactured device that is usually found wrapped around the human wrist. Its principle function is to indicate the time on either an anologue face (similar to a clock) with moving hands for hours, minutes and seconds or a digital face with large numbers (eg 1230). Newer wrist watches have additional functions including alarms, calenders, mobile phones, televisions, altimeters, timers, thermometers, diaries and games.
