Abstract: 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.

Abstract: A system (1) for a watch calendar includes: a first wheel (3); a first finger (5b) for driving the first wheel; a tooth (31b) for driving the first wheel, the tooth being movably mounted on the first wheel (3) between a retracted position and a driving position; and a desmodromic system (2, 4) having a cam (2) and a cam follower (4), the desmodromic system being arranged in such a way that at least a first position of the cam defines a first position of the follower permitting the retraction of the tooth, and that at least a second position of the cam defines a second position of the follower preventing the retraction of the tooth.

Abstract: Watch mechanism (100) including an element for the display of time, first and second elements (Q, PDL) for the display of first and second pieces of watch information derived from time, the mechanism including: —a first kinematic chain (CC1) for the simultaneous correction of time display, and the display of the first and second pieces of watch information; —a second kinematic chain (CC2) for the correction of the time display independently of the display of the second piece of watch information, and —a third kinematic chain (CC3) for the correction of the display of the second piece of watch information independently of the time display and the display of the first piece of watch information. The third chain includes an epicyclic gear train (TE) connected kinematically to the element (H) for the time display by a notched wheel (MC) included in the first and second kinematic chains.
