Abstract
The driving mechanism of the day of the month disk (18) comprises a driving wheel (14) and a transmission wheel (16) The driving wheel (14) comprises a toothed sector (26'a, 26'a) which can mesh with the pinion (44) of the transmission wheel (16) and peripheral wall surface (26'a) into which open the two ends (30' and 30'') of an arcuate groove (30). The transmission wheel (16) also comprises a member constituted by four arms (48a to 48d) carrying four studs (50a and 50d) which can enter the groove (30) and a pinion (52) which meshes with the disk (18). Outside the driving phases, two of the studs abut against the peripheral wall surface (26'b) in order to lock the disk (18). This mechanism provides for a low torque which enables the energy to be applied to the motor of the watch to be reduced.
