Abstract (en)
[origin: US2005254350A1] This mechanism comprises a date runner, a months satellite with five teeth on a pitch for twelve, secured to the date runner, a fixed planetary toothset and a drive member for driving the date runner comprising two drive fingers, the first intersecting the path of the toothset of the date runner, the second intersecting the path of the toothset of the months satellite. The latter is connected to the planetary toothset by a second satellite secured to it and the number of teeth of which is equal to a multiple of twelve, the number of teeth of the planetary toothset being chosen so that one of the five teeth of the months satellite is aligned with the axes of the satellites, of the drive member and of the date runner on the 30th of each month comprising less than 31 days.
