ELECTRONIC TIMEPIECE WITH WATER DEPTH METER

PURPOSE:To make compatible the water depth alarm function and time alarm function high in the untilization value by controlling an alarm drive signal generation circuit through an alarm time comparator circuit and a water depth value comparator circuit. CONSTITUTION:As the time measured with a time measuring circuit 3 coincides the set alarm time stored in an alarm time memory circuit 7, an coincidence output is outputted from an alarm time comparison circuit 8. On the other hand, a water depth comparison circuit 14 generates a different coincidence output as the water depth measured coincides with the set water depth. In response to these two kinds of coincidence outputs, an alarm signal generation circuit 15 generates different kinds of alarm signals to be applied to a buzzer driving circuit 16. This makes compatible the water depth alarm function, the time alarm function and the like high in the utilization value thereby achieving a higher safety of the diving work of the like.
