Abstract
A timepiece movement includes a motor that has a rotor for rotating an indicating hand, a control unit that rotates the rotor by using a main drive pulse and an auxiliary drive pulse, and that determines a reference position of the indicating hand by detecting a rotation state of the rotor when the indicating hand is rotated using a detection drive pulse based on the main drive pulse, a train wheel that transmits a drive force of the motor to the indicating hand, and that has an indicating hand gear and a second intermediate pinion which mesh with each other, and an elastic portion that is disposed in the indicating hand gear, and that is elastically deformed by coming into contact with the second intermediate pinion when the indicating hand is located at the reference position.
