ABSTRACT:
An electronic timepiece in which a higher frequency signal from a frequency standard is divided down to a lower frequency drive signal by a frequency converter. The drive signal is applied through a driver circuit to an electro-mechanical transducer which actuates time-representing members to indicate time. A control means is coupled to intermediate stages of the frequency converter and produces higher frequency drive signals. At least one contact plate made of flexible, electrically conductive material is adapted to be depressed from outside the watch case through a recess formed therein whereby the control means is connected to the driver circuit to apply the higher frequency drive signals to the electro-mechanical transducer thereby rapidly advancing the time-representing members.
