Abstract
PURPOSE: To shorten a fast advance time by lessening the width of fast advance pulses in accordance with a load applied to a step motor.
CONSTITUTION: This timepiece is equipped with fast advance switch 36, detection part 30 that detects the turning angle of the rotor of a pulse motor, pulse-width control circuit 32 that outputs a signal when the turning angle of the rotor reaches a fixed value, and fast advance signal generating circuit 34 that applies driving circuit 26 with fast advance pulses whose pulse width has been control by a signal from circuit 32. Then, the width of fast-advance driving pulses is reduced in accordance with a load applied to pulse motor 28.
