Abstract:
A timepiece includes a determination unit configured to execute determination processing of determining whether a braking force that brakes a rotor is preferably large or small, the rotor being rotated in a normal rotation direction to rotate a pointer clockwise; and a detection control unit configured to cause execution of rotation detection processing of detecting rotation of the rotor based on a first induced voltage output to a predetermined terminal among the first terminal and the second terminal being connected to a coil configured to generate a magnetic flux to rotate the rotor in the normal rotation direction, the predetermined terminal being selected based on the determination by the determination unit.
