Abstract
A step second timepiece comprises a quartz crystal oscillator and a frequency divider containing a reset circuit. The reset circuit includes a reset switch operable such that the time interval from when the reset switch is released up to when the next pulse is fed from the frequency divider is shorter than the pulse interval of the successive pulses fed from the said frequency divider thereby compensating for time lag associated with the release of the reset switch.
