Abstract

See full text

An electronic timepiece comprising counters and logic devices, in which the counters are utilized to memorize a variation of rate of the timepiece with respect to a time reference in response to actuation of a control means, and in which the logic devices are controlled by signals delivered by the frequency divider chain and are arranged to periodically effect automatic correction of the variation of rate by an amount equivalent to the value memorized in the counters. The invention relates to a timepiece which permits the user to himself adjust the rate of his watch by means of a simple manipulation not requiring any complicated adjustment of electronic circuits, and which further performs an automatic correction of the variation of rate.
