A
watch is a small portable
timepiece or
clock that displays the
time and sometimes the
day,
date,
month and
year. In past centuries, these often took the form of
pocket watches, which today are seldom carried or worn. In modern usage,
watch is usually a contraction of
wristwatch,
a designation for the most popular style of timekeeping device worn on the wrist.
Because most watches lack a striking
mechanism, such as a bell or gong to announce the passage of time, they are properly designated as
timepieces,rather than clocks.
