Abstract
L'INVENTION CONCERNE UN DISPOSITIF CHRONOMETRIQUE ELECTRONIQUE A AFFICHAGE ANALOGIQUE, OU A AIGUILLES SIMULEES. IL COMPORTE UN DISPOSITIF D'AFFICHAGE ELECTRO-OPTIQUE QUI SIMULE UN MOUVEMENT D'HORLOGERIE MECANIQUE. UNE MATIERE ELECTRO-OPTIQUE, PAR EXEMPLE UN CRISTAL LIQUIDE, EST EXCITEE DANS DES REGIONS DETERMINEES POUR CHANGER SON APPARENCE ET SIMULER AINSI LE MOUVEMENT DES AIGUILLES. L'INVENTION S'APPLIQUE NOTAMMENT AUX MONTRES ELECTRONIQUES.
