摘要： The present invention relates to a timepiece comprising an at least annual date mechanism (1) which comprises a month-management cam (2), a large lever (4) arranged to cooperate with said month-management cam, a date-indicating mechanism, a month-indicating mechanism, and at least one mechanism for independent correction of the date or month comprising at least one date-correcting or month-correcting member, respectively, arranged to cooperate with said date-indicating or month-indicating mechanism, respectively. The date-correcting or month-correcting mechanism, respectively, comprises a date-correcting cam (50) or a month-correcting cam (22), respectively, mounted so as to be freely rotatable, a date-correcting or month-correcting stem, respectively, which can be rotated in order to rotate the date-correcting cam (50) or the month-correcting cam (22), respectively, said date-correcting cam (50) or month-correcting cam (22), respectively, being arranged so as to, during rotation thereof, drive the large lever (4) in order to isolate said large lever (4) at least from the month-management cam (2) before the date or month is corrected, respectively, and to drive the actuation of the date-correcting or month-correcting member, respectively, in order to subsequently correct the date or month, respectively, the rotation of the date-correcting or month-correcting cam, respectively, being controlled solely by rotation of the date-correcting or month-correcting stem, respectively.

摘要： The movement transmission system (90), notably for a timepiece calendar system (200), includes a driving mobile (4) pivoted about a first axis (A4) and has a driving toothset (42) distributed over a curved profile (43); a driven mobile (7) pivoted about a second axis (A7) and having a driven toothset (72); an intermediate pinion (8) pivoted about a third axis (A8) and having a toothset (81) driven by the driving toothset (42) and driving the driven toothset (72); the toothset (42), the curved profile (43), the driven toothset (72) and the toothset (81) being arranged at a same level or in a same plane, and the driving mobile (4), the driven mobile (7) and the intermediate pinion (8) being arranged so that the driving mobile (4) moves the driven mobile (7) via the intermediate pinion (8) through 1/m steps for at least some steps of the driving mobile (4), m being a real number greater than 1, and so that the driving mobile (4) can define an angular position, with minimum play, of the driven mobile (7) via the pinion (8), whereas the driving mobile (4) is in a given angular position.

摘要： Calendar mechanism for timepieces, displaying the duration of the current month and comprising a month cam whose periphery is accessible to a feeler-spindle of a perpetual calendar device to obtain the duration of the current month, this calendar mechanism and the month cam being updated monthly on each current month change by the perpetual calendar device, the month cam is generalised to an integer number of years each including a virtual 28-day month of February, the calendar mechanism includes a leap year mechanism, external to the month cam, and which is arranged to insert radially, every four years in February, a first corrector finger between the periphery and the feeler-spindle to inform the latter that the current month of February has 29 days instead of 28.
