Principle and working of a stop watch

A stopwatch is a handheld timepiece used to measure the amount of time elapsed from a particular time when it is started, to the time when the piece is stopped. A stopwatch can be mechanical, resembling a pocket watch with an analog or digital face. Digital stopwatches are more accurate. Mechanical stopwatches are powered by a mainspring, which must be periodically wound up by turning the knurled knob at the top of the watch. It is designed to be manually started, for example at the beginning of an event, then stopped with the press of a button at the exact moment a runner crosses a finish line or a swimmer reaches the end lap, etc.
