Abstract

L'invention concerne l'horlogerie. Dans une pièce d'horlogerie électronique dans laquelle un moteur 4 alimenté en énergie électrique fournit de l'énergie mécanique pour entraîner un organe d'affichage des informations horaires 5, des moyens de contrôle 6-7 permettent périodiquement de mettre en évidence une erreur de position éventuelle de l'organe d'affichage, tandis que des moyens de commande du circuit d'alimentation 3 permettent de rapprocher l'énergie électrique fournie de celle qui correspond à l'énergie mécanique minimum requise pour que l'erreur soit nulle. L'invention permet ainsi de réduire la consommation d'énergie électrique.
