ABSTRACT:
An electronic watch comprising a precision resonator and oscillator connected to a frequency divider which produces impulses of 1 H.sub.z. Connected to the frequency divider in sequence is a seconds counter, a minutes counter, an hour counter and possibly a day counter. An electronic means serves for displaying the state of the counter, and a microswitch including an actuator activated externally of the watch by finger pressure, acts to reset the seconds counter to zero and acts concurrently on all or part of the divider, independently of the minutes and hours counters, the actuator being isolated from or combined with the normal device to reset the time or correct the date. The seconds counter is constructed as a series of counter units, the last of which is a binary counter and all of the units are reset to zero when the switch is closed. In this way errors of thirty seconds or less can be corrected by acting on the actuator.
