Abstract (en)
[origin: EP1868047A1] The timepiece has a date mechanism with a month module comprising a cam advancing in step per month. A correction module (28) is driven by a minute gear train and cooperates with the module. The module (28) has a mobile (28a) cooperating with a correction wheel (18a) for advancing the wheel, for number of steps equal to day of the month and less than 31. The wheel (18a) has a spring (18d) and a jumper (22) that are connected to a display wheel (18b) for permitting it to advance, in end of month, for number of steps equal to that advanced by the wheel (18a) during the month that is completed.
