Abstract

PURPOSE:To operate the watch by low electric power by arranging a magnetic sensor in a magnetic circuit of a stepping motor and controlling the driving condition of the stepping motor by the sensed signal of said magnetic sensor. CONSTITUTION:Magnetic resistor elements 4 and 5 are arranged in a gap in a yoke 1 of the step motor so that the directions of the magnetic fields are opposite to each other. Said magnetic resistor elements 4 and 5 are connected in series, the direction 1 of the magnetic field of the yoke 1 is sensed, and the rotation of a rotor 2 is sensed. If the rotor 2 is not normally rotated, compensating pulses are applied or the electric power is increased.
