Timepiece and motor control method

A motor control method performed by a motor drive device, which includes a stepping motor in which a rotor magnetized in two poles is rotationally driven in a stator connected to a driving coil, a drive circuit that applies a first drive pulse having a stable stationary position at a rotor rotation angle of 90 degrees or less from a reference position and a second drive pulse having the stable stationary position at a rotor rotation angle of 90 degrees or more from the reference position, as a drive pulse that is a pulse for driving the rotor, to the driving coil, and a control circuit that controls application of the drive pulse by the drive circuit, the motor control method comprising:

• a control step of, when a period during which the drive pulse is not applied to the driving coil is assumed as a waiting period, controlling the drive circuit to generate the waiting period after a first application of the second drive pulse after an application of the drive pulse to the driving coil is started and rotate the rotor by one or more turns without passing through the waiting period at at least one predetermined timing that is determined in advance after the waiting period.
