Most sport events would not be complete without a stopwatch. With a push of a button, it is manually started and stopped to measure the amount of time that has elapsed. Aside from a timer, a stop watch can also have features like a calendar or alarm. A sport stop watch is a handheld timepiece. The larger digital version that we see in sports stadium which allows us to view time from a distance is called a stopclock.

A stopwatch can either be mechanical (analog) or digital. The first is often preferred for its traditional look, which resembles a pocket watch. That is why it is a popular gift for coaches or trainers. The second type is more accurate and is often used in larger competitions. A stop watch is not only used in sports. It can be used by anybody who needs to measure exact timing.
