Abstract:
A timepiece, in which an indicating hand is driven by a motor and high speed processing is required for driving a load other than the indicating hand, includes a main control circuit that instructs drive timing of the motor so as to drive the load, and that is operated by an operation frequency serving as a first frequency, and a motor control unit that generates a drive pulse for driving the motor, and that is operated by an operation frequency serving as a second frequency which is lower than the first frequency.
