To provide an analog electronic timepiece capable of driving a motor by a drive pulse having a narrow pulse width without deteriorating mechanical strength of a stator. A control circuit controls a switch in a normally closed state and switches through in a normally opened state, controls the switch to a closed state at an initial period of a drive pulse when the drive pulse is supplied to a motor via a motor driving circuit and controls the switch to a closed state during a successive period successive to the initial period. Thereby, the motor is supplied with the drive pulse having a predetermined wave height value during the initial period and the drive pulse having a wave height value smaller than the predetermined wave height value and capable of controlling to rotate the motor during the successive period, a saturation time period of a saturable portion in a stator of the motor is shortened and the motor is driven by a drive pulse having a narrow pulse width.
An analog electronic timepiece characterized in that in an analog electronic timepiece for controlling to rotate a motor for driving a time hand by supplying a drive pulse from motor controlling means to the motor and indicating time by the time hand driven to rotate by the motor:
