Abstract

PURPOSE: To always secure the accurate setting of the time signal for the electronic watch having the hands, by counting the time difference at least between the two among the time of the time signal, the display time and the present time each.
CONSTITUTION: With operation of operation unit 11 for setting of time signal, the forward turn quick sending signals are applied to step motor 4 from control circuit 12. And the watch gains by the amount equivalent to the contents of time difference counter 13. However, in case the display does not indicate the hour on the hour, hand 5 is set to the hour on the hour via unit 11. At this moment, the contents of counter 13 memorizes the difference to the present time, and display difference counter 14 becomes 0. Whenu unit 11 is operated again, the reverse quick sending signals are transmitted to motor 4 from circuit 12. And motor 4 receives the backward turn continuously until the contents of counter 14 becomes identical to counter 13, and display 5 is returned to the present time. After this, time signal 10 is given every time when hour difference counter 13 of the 1-hour counter becomes 0.
