Abstract

Le mouvement de la montre comprend deux moteurs (18 et 19) actionnant respectivement les aiguilles d'heures et de minutes et une aiguille de secondes indépendantes. Le train d'engrenages (20a, 21, 22 et 23) reliant le rotor (20) du moteur (18) à la roue de centre (25) ne passe pas par le centre du mouvement mais le contourne. La mise à l'heure manuelle des aiguilles d'heures et de minutes s'effectue à l'aide d'une tige de commande (41) permettant d'actionner manuellement le renvoi de minuterie.
