Abstract
An electronic timepiece havng an integrated electronic circuit including a quartz crystal oscillator, connected to a multi-stage divider, which divider supplies various outputs of various frequencies to corrector circuits, a logic circuit and a motor control circuit. The motor control circuit includes a switch to allow the timepiece to be stopped by resetting at least one stage of the divider. One of the terminals of the motor is connected to one of the stages of the divider to allow the control of the frequency of the signal issued from this stage, and, therefore, the frequency of the quartz oscillator.
