Abstract
A stopwatch has a measuring section for measuring a primary physical quantity, a memory section for previously storing as a target value the value of the primary physical quantity at a point where a time is to be recorded, and recording sections for recording a measured value of time at a time point when the value measured by the measuring section becomes equal to the target value, after initiation of measurement of time. The target value is, for example, a value actually recorded before initiation of measurement of time by the measuring section at the point where time is to be recorded.
