ABSTRACT:
An electronic timepiece is provided with a correction signal generating system for producing correction pulses to modify current time or other data. The system includes a rotary switch, coupled to a timepiece crown to be rotated thereby and having a plurality of fixed and movable contacts, with the number of movable contacts being less than the number of fixed contacts, and circuit means for producing a train of correction pulses from either of two output terminals in accordance with the direction of rotation of the timepiece crown. Correction pulses from one of these output terminals serves to increment the quantity being corrected, while correction pulses from the other output terminal serve to decrement that quantity. Gearing may be provided between the crown and the switch rotor, to increase the maximum rate of generation of correction pulses.
