A timepiece includes a voltage detection unit that detects a voltage applied to a stepping motor for driving an indicating hand, and that outputs a voltage detection result, and a drive control unit that controls a rotor to perform reverse rotation by using a reverse rotation pulse including a first pulse whose polarity is the same as that of a normal rotation pulse for causing the rotor of the stepping motor to perform normal rotation, a second pulse whose polarity is reverse to that of the first pulse, and a third pulse whose polarity is reverse to that of the second pulse, and to control the rotor to perform the reverse rotation by using the third pulse having a pulse width set in accordance with the voltage detection result.
A timepiece comprising:
A control method of a timepiece, comprising:
