PURPOSE:To facilitate the time correction of the watch with alarm in which an electro-optical dispaly device is provided in combination, with a simple constitution by simultaneously correcting the hands and the electro-optical dispaly device with the fast feed pulses being generated according to operating speeds. CONSTITUTION:When an operating member 34 is operated, the differentiation signal from a differentiation circuit 38 is applied to the down counter 42 of a fast feed pulse generating circuit 40 via AND gate 44, and the set jam data number becomes zero, by which an AND gate 46 is opened until the output of the counter 42 inverts. As a result, the fast feed signal from a frequency dividing circuit 42 is simultaneously applied via gate 46 to the driving circuit 8 of a hand displaying motor 12 and the dispaly driving circuit 20 of an electro-optical display device 22, and the time correction of the watch provided with an alarm device and provided with a combination of the hands and electro-optic dispaly device is readily accomplished by the simple constitution of not reguiring any mechanical mechanism. According to the operating speed, the jam set value of the circuit 40 is changed by the carrier signal generated from a counter 60, then the time correction speed changes according to the operating speeds of the member 34. |
