ABSTRACT:
In a stop watch, when a switch is depressed, hands are operated to start timing. Every time a split time switch is depressed, the time intervals between time points at which the split time switch is depressed are sequentially stored in a memory. Therefore, when the switch is re-depressed, the stop watch terminates its time measurement. A plurality of split times up to the end of time measurement can be reproduced, from the latest split time to the earliest split time.
