In an analog electronic timepiece in which the rotation of a rotor (1a) step motor (1) is decelerated through train wheels before it is transmitted an hour hand (17) and a minute hand (15), the gravity center of a center wheel composed of a center wheel gear (9), a center wheel pinion (10), and a center wheel shaft (11) to which the minute hand (15) is mounted is displaced from the axis of the center wheel shaft (11) to within an angle range of less than ±90° with respect to the opposite direction to a direction in which a time indicating part (15a) of the minute hand (15) extends so as to reduce a moment on the center wheel shaft (11) caused by a combination of the minute hand (15) and the center wheel. This makes it possible to prevent a hand-skip due to disturbance even if the value of holding energy of the step motor (1) is reduced.
