A stopwatch measures elapsed time from start to stop, while a timer counts down from a set time to zero. Stopwatches are for measuring how long something takes, timers are for knowing when a set time has passed.
Modern digital stopwatches are extremely accurate, typically measuring time to within 0.01 seconds or better. They use quartz crystal oscillators for precise timekeeping.
Lap time refers to the time elapsed between recording laps. It allows you to measure segments of a longer activity without stopping the overall timing.
Most stopwatches measure forward from zero. However, countdown timers (which are different from stopwatches) do count backwards from a set time to zero.
Stopwatches provide precise timing for performance measurement, allowing athletes to track improvement, set goals, and analyze their training effectiveness.
For synchronized timing, use a single master stopwatch or employ electronic timing systems. Manual synchronization between multiple watches is inherently imprecise.
