Abstract

L'invention concerne l'horlogerie. Outre les éléments classiques, à savoir un oscillateur 1, un diviseur 3, un circuit d'attaque 4, un moteur pas à pas 5, et un dispositif d'affichage 6, une montre électronique comporte un circuit d'entrée 7, un circuit de commande 9 et un circuit d'arrêt d'avance rapide 10, qui permettent de mettre la montre à l'heure en attaquant le moteur pas à pas avec des impulsions de cadence plus rapide que les impulsions normales. On effectue la mise à l'heure en actionnant un interrupteur 8 qui est manoeuvré par la rotation d'une tige. Application aux montres électroniques à affichage analogique.
