Abstract

La présente invention concerne une montre électronique à aiguilles ayant les fonctions de commandes les plages alternatives de fonctionnement des aiguilles et ainsi permettant la fourniture de diverses indications. Cette montre comporte des aiguilles (101, 102) donnant l'heure, des premières et secondes aiguilles (103, 104) installées séparément des aiguilles des heures et minutes (101, 102), un moteur (200) tournant en marche avant et arrière alternativement un certain temps défini, un train d'engrenages qui transmet le mouvement de rotation du moteur (200) de façon à faire tourner en mouvement alternatif les premières et secondes aiguilles (103, 104) dans deux sens opposés l'une par rapport à l'autre dans les plages définies, un élément support supportant les pignons constituant le train d'engrenages, et un organe de commande commandant la rotation des premières et secondes aiguilles (103, 104) selon des plages de commande définie en commandant la plage de rotation des pignons (211) contenus dans le train d'engrenages, auquel cas un espace (200) est ménagé dans l'élément support à la place des pignons (211) dont la plage de rotation est commandée par l'organe de commande de façon à agencer les autres pignons (229) de façon que les autres pignons (229) puissent être agencés dans le train d'engrenages.
