Abstract

An electronic timepiece provides continuous rotation for a hand in response to a discrete driving rotation. An energy storage mechanism is coupled to the discrete driving rotation and converts the discrete driving rotation into stored energy. A control mechanism continuously releases the stored rotational energy as continuous rotation. A linkage coupled between the energy storage mechanism and control mechanism transmits continuous rotation therebetween and drives the hand in a continuous sweeping manner.
