An electrical timepiece comprises external input units for receiving an external
input signal, a motor unit for driving an analog hand unit for displaying time,
a battery unit capable of charging, a voltage detect circuit for measuring the
voltage of the stored electricity in the battery and comparing the voltage with
a reference voltage, and a stored electricity unit discharge control circuit for
starting discharge from the battery when an external input signal is received by
one of the external input unit, and for stopping discharge from the battery when
the comparison result by the voltage detect circuit satisfies a prescribed condition.
