<p>The device has a disk (1) of days and a disk (2) of dates, where one of the disks acts as a dial. The dial has an aperture (2.1) allowing the dial to see inscription of a current month on a disk (3) of months, where the disk is driven, either directly or indirectly, by a timepiece movement of a timepiece. A correction mechanism cooperates with a gear train driving the disk of months, either directly or indirectly, starting from the movement. The mechanism is provided to advance and reverse the disk of months so as to change the month displayed on the dial in a bidirectional manner.</p> |
