摘要：A timepiece movement includes a stepping motor having a rotor for rotating an
indicating hand, and a control unit for rotating the rotor by using a main drive pulse andan auxiliary drive pulse. When the indicating hand is rotated using a detection drive pulsebased on the main drive pulse, the control unit determines a reference position of theindicating hand by detecting a rotation state of the rotor.
