Abstract

L'invention concerne les montres électroniques. Dans une montre à affichage analogique par cristaux liquides, les aiguilles d'une montre classique sont simulées par des éléments d'affichage 15, 16, 17, en forme de segments, qui sont actionnés sélectivement pour indiquer l'heure, la minute et la seconde. Un commutateur permet de remplacer cet affichage par un affichage de calendrier qui indique le mois, le quantième du mois et le jour de la semaine, toujours sous une forme analogique. Application à l'horlogerie.
