Abstract
An electronic timepiece having a step motor is driven by a drive circuit which selectively produces either continuous hand-carrying pulses or stepwise hand-carrying pulses. The continuous hand-carrying pulses are produced by a continuous hand-carrying waveform shaping circuit connected to a frequency divider, and the stepwise hand-carrying pulses are produced by a stepwise hand-carrying waveform shaping circuit connected to the frequency divider. The selection of either the continuous hand-carrying pulses or the stepwise hand-carrying pulses is executed by a hand-carrying mode selection circuit in response to the operation of a reset switch for resetting the frequency divider.
