发明名称 ANALOG ELECTRONIC TIMEPIECE
摘要 An analog electronic timepiece capable of decelerating the rotation of a rotor (1a) of a step motor (1) through a train wheels before it is transmitted to an hour hand (17) and a minute hand (15), wherein the gravity center of a second shaft rotating body comprising a center wheel gear (9), a center wheel pinion (10), and a second shaft (11) to which the minute hand (15) is installed is displaced by an angle range of less than +/-90 DEG , from the axis of the second shaft (11), in the direction opposite to the direction in which a time indicating part (15a) of the minute hand (15) is extended so as to reduce a moment on the second shaft (11) caused by the minute hand (15) and the second shaft rotating body, whereby a breakage of the hand due to disturbance can be prevented even if the value of the holding energy of the step motor (1) is reduced.
