  • Patent number: 4050234
    Abstract: A hand-return mechanism for an electronic timepiece wherein at least one hand is returned to a predetermined position and the motor rotating same is correspondingly adjusted. The timepiece includes a display hand mechanically coupled to a positionable gear, the rotational position of the gear determining the rotary position of the hand. An oscillator circuit produces a high frequency time standard signal and a divider circuit produces an alternating polarity pulse of a predetermined low frequency in response to the high frequency time standard signal. An electro-mechanical converter is adapted to rotate the gear by means of a rotor in response to the period of the alternating polarity pulse applied thereto.
