Abstract

In an electronic unit having a plurality of motors, a reduction in power-supply voltage is suppressed even if the plurality of motors are driven, and a difference in hand moving timing is allowed to be made inconspicuous. An electronic timepiece having a seconds motor for driving a seconds hand and an hour-and-minute motor for driving hour and minute hands, which serves as an electronic unit, moves the seconds hand and the hour and minute hands such that, when a seconds auxiliary pulse signal is output to the seconds motor at the hand moving timing of the seconds hand, control is applied in a way in which neither magnetic-field detection around the hour-and-minute motor nor the rotation detection of the hour-and-minute motor is performed at the hand moving timing of the hour and minute hands, and an hour-and-minute auxiliary pulse signal is output to the hour-and-minute motor.
