Abstract

Rouage de mouvement d'horlogerie électronique à cristal de quartz et à affichage analogique comprenant un oscillateur à cristal de quartz servant de base de temps, un transducteur électro-mécanique et une roue des secondes supportant une aiguille des secondes. Afin de réduire l'encombrement général du mouvement de la montre, l'invention prévoit que le rouage inclut au moins deux roues dentées 11, 12 entre le transducteur électro-mécanique 16 et la roue des secondes 8. Application à la construction des montres-bracelets électroniques à cristal de quartz et à affichage analogique
