Abstract
An electronic timepiece, including: a motor having a rotor and at least two coils, the rotor being configured to rotate to a plurality of prescribed positions; and a driving processor for driving the motor, the driving processor being configured to: generate a detection pulse for detecting whether or not the rotor has rotated; cause the generated detection pulse to be applied to at least one of the at least two coils; receive a signal indicating a detected value of current flowing in the at least one of the at least two coils that is generated in response to the detection pulse outputted to the at least one of the at least two coils; and determine whether or not the rotor has rotated to one of the plurality of prescribed positions on the basis of the detected value of current.
