Abstract

PURPOSE: To realize an alarm watch with nearly the same constitution as the conventional watch for the electronic watch featuring the hand display, by processing the alarm function through the electronic circuit and without using any mechanical contact or the like.
CONSTITUTION: Operation unit 18 is operated for setting of the alarm, and thus the signals to give the quick sending to step motor 4 are transmitted from control circuit 10. Thus the alarm time is displayed to display unit 5, and at the same time the time difference to the present time is memorized in time difference counter 11. When unit 18 is operated again, the signals to give the reverse quick sending to motor 4 are transmitted from circuit 10. At the same time, display difference counter 15 counts these signals continuously until coincidence 17 is obtained with the contents of counter 11 to return display 5 to the present time. After this, counter 11 receives the subtraction via the normal hand movement signals of motor 4. And when the contents of counter 11 becomes 0, alarm 9 is generated. At the same time, another alarm time is set to time difference counter 12.
