Hand position identification device, timepiece, and hand position identification method

A hand position identification method in a hand position identification device including a motor having a rotor and a coil, an indicating hand rotated by the motor, a rotation detection unit for detecting a rotation state of the rotor by using an induced voltage generated in the coil, and a storage unit, the method comprising:

• a step of causing the rotation detection unit to detect the rotation state of the rotor by using the induced voltage generated in the coil after a drive pulse is output to the coil;
• a step of causing a control unit to store a timing information piece relating to a timing at which the induced voltage exceeds a predetermined threshold, in a storage unit;
• and
• a step of causing the control unit to compare a first timing information piece stored in the storage unit, which is a timing information piece obtained in a case where the indicating hand is located at a first indicating hand position, with a second timing information piece which is a timing information piece obtained in a case where the indicating hand is located at a second indicating hand position, and causing the control unit to identify the second indicating hand position as an identified position in a case where a difference between the first timing information piece and the second timing information piece is equal to or more than a predetermined amount.
