stopwatches
Lap time keepers
Stopwatches are timing devices designed to measure elapsed time with precision.
A stopwatch starts, stops, and resets on command, making it essential for racing, athletics, and scientific experiments.
The coach clicked his stopwatch as runners crossed the finish line.
Digital versions have largely replaced mechanical ones, though the term persists regardless of technology.
