PROBLEM TO BE SOLVED: To introduce an endshake micrometric adjustment mechanism in a timepiece mechanism.SOLUTION: A device 1 for micrometric adjustment of the endshake of a timepiece wheel set in axial direction relative to a structure includes a slewing bearing 4 for the wheel set, to form an axial stop member for the wheel set in the axial direction. This device includes an adjustment stage 5 having a variable thickness in the axial direction, and the adjustment stage 5 includes elastic return means 9 which pushes a first component 6 including rotational driving means 7, and the rotational driving means 7 can be operated by a tool, and the bearing 4 is installed on a second component 8 fixed to the structure directly or via at least one case 10. The elastic return means 9 is supported on the structure directly or via the at least one case 10. |
