摘要: A timepiece includes pointers, motors for driving the a pointer position detector detecting positions of control unit, an electricity storage unit as power supply, and voltage supply voltage. The controls detection by means on basis detected detector. Therefore, can be halted when decreases to less than specific voltage, driven while is low.
