About Stopwatches
A stopwatch is a timepiece designed to measure the amount of time that elapses between its activation and deactivation. Unlike a regular clock that shows the time of day, a stopwatch measures elapsed time.
History of Stopwatches
The first stopwatch was invented by Samuel Watson in 1690, but the first modern stopwatch was created by Tag Heuer in 1820. Digital stopwatches became common in the 1970s with the advent of LED and LCD displays.
Uses of Stopwatches
- Sports: Timing races, training sessions, and athletic performances.
