An electronic timepiece includes a power generator that generates electric energy, a power storage that stores the electric energy, a capacity detector that detects remaining capacity of the power storage, an operation unit, an operation detector that detects a measurement display operation for instructing the operation unit to display a measurement time, and a capacity display operation for instructing the operation unit to display the remaining capacity, an indicating hand that is used in displaying the measurement time and the remaining capacity, a drive unit that drives the indicating hand, and displays the remaining capacity after moving the indicating hand so as to indicate a preset reference position.

Electronic timepiece and display control method of electronic timepiece

A stepping motor control circuit includes a drive pulse generation section that generates forward-rotation drive pulses that drive a stepping motor stepwise in a forward rotation direction and reverse-rotation drive pulses that drive the stepping motor stepwise in a reverse rotation direction and a forward/reverse rotation switching control section that switches the drive pulses outputted to the stepping motor from one of the forward-rotation drive pulses and the reverse-rotation drive pulses to the other, and the forward/reverse rotation switching control section switches the drive pulses outputted to the stepping motor from one of the forward-rotation drive pulses and the reverse-rotation drive pulses to the other and then provide a predetermined period before the other drive pulses are outputted to the stepping motor.
