<p>PURPOSE:To improve analog timepieces in alarm timing accuracy with a normal time indicator and an alarm setting time indicator driven by different electromechanical converters and alarm is emitted when the count values of a time counter and an alarm setting counter circuit agree with each other. CONSTITUTION:The first stem 9 rotates the first train wheel 15 independently from the first electromechanical converter 14 to mechanically correct the first analog indicator mechanism 16. Further, the stem 9 resets a time counter 18 and an alarm setting counter circuit 21. The second stem 10 sets an alarm 19 to ON or OFF and the result of this setting is displayed on a dial 20. The stem 10 drives an electromechanical converter 23 to turn an alarm timing pointer 6 for the hour and an alarm timing pointer 7 for the minute and set an alarm setting counter circuit 21. The alarm 19 actuates when the count values of the counter 18 and circuit 21 agree with each other.</p> |
