    • A timepiece movement includes a second light emitting element, a second light receiving element, and a second wheel & pinion that drives a second hand and that has a first second wheel transmittable portion and a second second wheel transmittable portion through which light is transmittable, A control unit detects a position of the second wheel & pinion by causing the second light receiving element to receive the transmitted light emitted from the second light emitting element and transmitted through the first second wheel transmittable portion or the second second wheel transmittable portion, and a second detection wheel has a second detection wheel transmittable portion through which the transmitted light is transmittable. The control unit detects a transmitting time point at which the transmitted light is transmitted through the first second wheel transmittable portion or concurrently through the second second wheel transmittable portion and the second detection wheel transmittable portion. After the transmitting time point, when the second detection wheel transmittable portion is located at other positions except for a second detection position where the second detection wheel transmittable portion is located at the transmitting time point, the control unit causes the second light emitting element to stop light emitting.
