ABSTRACT:
In a stopwatch of this invention, when a lap switch is operated after time measurement is started, a lap time from the immediately preceding lap switch operation to the current lap switch operation is stored and compared with a measurement time after the current lap switch operation. Since an alarm tone is generated if the measurement time after the current lap switch operation coincides with the stored lap time, the immediately preceding lap time can be used as a target time of the time measurement. The stopwatch can be conveniently used when a running speed is increased or decreased in each lap in a track race or the like.
