ABSTRACT:
A time indication setting circuit for accelerating or stopping the advance of the time indicating mechanism in an electronic timepiece. A delay circuit receives time pulses developed within the timepiece and the time pulses and delayed time pulses from the delay circuit are applied to a gate circuit. The gate circuit applies the time pulses and the delayed time pulses, under the control of a control circuit, to the timepiece drive train to drive the timepiece time indicating mechanism at a rate determined by the pulse repetition rate of the pulses applied to the drive train. The control circuit is manually operable to apply the control signal so the gate circuit applies both the time and the delayed time pulses to the drive train and thereby accelerates the advance of the time indicating mechanism, or to block both the time and the time indicating pulses and thereby stop the advance of the time indicating mechanism or to apply only the time pulses to the drive train so that the time indicating mechanism advances at a normal rate.
