Abstract

L'invention concerne les montres électroniques. Une montre électronique possède un moteur pas à pas 55 qui est associé à un circuit d'attaque 54, un circuit de commande 56 et un circuit de détection 57. Le circuit de détection 57 détecte une absence de rotation du moteur sous l'effet d'une impulsion d'attaque normale, et il provoque alors l'application au moteur d'une impulsion d'attaque de correction, de largeur supérieure aux impulsions normales. Application aux montres électroniques à affichage classique.
