Abstract
Pièce d'horlogerie comprenant une roue de vingt-quatre heures (123456.50) ayant trois dents longues (6.40, 6.50, 12.41) emmenant une roue de quantième (1.60) supportant une série de rouages dont les dents sont mues par les dents longues de la roue de vingt-quatre heures, de sorte que la date soit automatiquement ajustée et indiquée pour tous les mois longs ou courts. Cette pièce d'horlogerie permet un ajustement en avant et en arrière de la date, du jour, du mois et de l'année bissextile par la couronne de remontoir. Timepiece comprising a twenty-four hour wheel (123456.50) having three long teeth (6.40, 6.50, 12.41) carrying a date wheel (1.60) supporting a series of cogs whose teeth are driven by the long teeth of the twenty-four hour wheel, so that the date is automatically adjusted and indicated for all long or short months. This timepiece allows the date, day, month and leap year to be adjusted back and forth by the winding crown.
