    The invention relates to a watch comprising at least one such movement.
    The invention relates to the field of winding and setting time watches, and control mechanisms of push-button watches or control tabs.
    BACKGROUND OF THE INVENTION [0005] The meshing between wheels or toothed gears carried by different axes, during axial movement of one of the antagonistic components, often results in a tooth to tooth shock, which stresses the teeth in shear, and leads quickly to their damage. This is particularly the case when pulling a time-setting rod, which is maneuvered by the user in a sudden movement and with a traction force which is not limited, and which is disproportionate by compared to the dimensions of the components. SUMMARY OF THE INVENTION [0006] The invention proposes to implement means sparing the teeth during maneuvers of the rod, or, more generally, pushbuttons or control rods which a watch is equipped with, and which have a toothing designed to mesh, in a particular position, with another toothing of another component of the movement.
    For this purpose, the invention relates to a time-setting mechanism for pocket watch or wristwatch, comprising a movable time-setting rod along a first axis between at least one rest position and a time setting position, and movable pivotally about said first axis, and comprising at least a first toothing arranged to cooperate, in at least said axial position of time setting of said rod, with at least a second toothing of a return which still comprises said mechanism, said return being pivotally mounted about a second axis, characterized in that at least, or said first toothing has first surface tooth entrances oblique with respect to said first axis, or said second toothing comprises second surface tooth entries oblique with respect to said first axis, to prevent damage to said first toothing or / and said second toothing during a maneuver axial of said rod along said first axis, when a tooth recess of said first toothing, respectively second toothing, is not aligned with a tooth crown of said second toothing, respectively first toothing.
    The invention also relates to a watch movement comprising at least one such time setting mechanism.
    The invention relates to a watch comprising at least one such movement.
    BRIEF DESCRIPTION OF THE DRAWINGS [0010] Other features and advantages of the invention will appear on reading the detailed description which follows, with reference to the appended drawings, in which: FIG. 1 represents, schematically and in perspective, a watch setting mechanism according to the invention, with a time-setting rod, carrying a first toothing, being pulled to mesh with a return axis parallel to his and bearing a second set of teeth; fig. 2 represents, schematically and similar to FIG. 1, the beginning of the meshing; fig. 3 represents, schematically and similar to FIG. 1, the end of the meshing, with full cooperation of the teeth in position of setting time; fig. 4 represents, schematically, partially, the first toothing and the second toothing in section in a common plane intermediate to the two axes of pivoting of the rod and the return, in the approach position of FIG. 2; fig. 5 is similar to FIG. 4, these two teeth in the meshing start position of FIG. 2; fig. 6 shows, similarly to FIG. 4, these two teeth in the fully meshing position of FIG. 3, in the time setting position T1 of the rod;

    fig. 7 is a block diagram showing a watch having a movement which incorporates a time setting mechanism according to the invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0011] The invention relates to the field of winding and setting mechanisms for watches, and control mechanisms for push-button watches or control tabs, toothing designed to mesh, in a particular position, with another toothing of another component of the movement. The invention is described in a particular application and advantageous to a winding mechanism and time setting. The watch designer will be able to apply it to another order such as chronograph control, time zone, minute repeater, or similar. The invention thus relates to a time setting mechanism 1 for a pocket watch or wristwatch, comprising a rod 2 for setting the time. This rod 2 is movable along a first axis D1 between at least one rest position TO and a setting position time T1. The rod 2 is pivotally movable about the first axis D1, and it comprises at least one first toothing 3. This first toothing 3 is arranged to cooperate, in at least this axial position setting time T1 of the rod 2, with at least a second toothing 4 of a return 5 which still includes the mechanism 1. This reference 5 is pivotally mounted about a second axis D2, preferably parallel to the first axis D1. According to the invention, at least one of the teeth 3 and 4 comprises an oblique toothing with respect to the axis D1, to prevent damage to the first toothing 3 and / or the second toothing 4 when axial operation of the rod 2 along the first axis D1, when a tooth cavity of the first toothing 3, respectively second toothing 4, is not aligned with a tooth crown of the second toothing 4, respectively first toothing 3 - or the first toothing 3 has first tooth inlets 6 of oblique surface with respect to the first axis D1, - or the second toothing 4 has second tooth entrances 7 of oblique surface relative to the first axis D1, - or the first toothing 3 and the second toothing 4 each comprise first, respectively second, tooth entries 6, respectively 7, of oblique surface relative to the first axis D1. Preferably, the second axis D2 is parallel to the first axis D1, and both the first toothing 3 and the second toothing 4 respectively comprise first tooth inlets 6 and second tooth inlets 7 of oblique surface relative to at the first axis D1. Preferably, the first toothing 3 comprises a first useful meshing portion 30 constituting an engagement surface, and the second toothing 4 comprises a second useful meshing portion 40 constituting an engagement surface. And, in the position T1 of cooperation between the first toothing 3 and the return 5, the first useful meshing part 30 and said second useful meshing part 40 cooperate on a contact surface 10 between the useful intermeshing parts 30 and 40, over the entire surface of the smallest of the useful meshing parts 30, 40, as visible in FIG. 6. [0017] And the oblique surfaces of a tooth of the first toothing 3 or of the second toothing 4 are beyond the engagement surface of the tooth of the other of the first toothing 3 or second toothing. 4. [0018] And in a particular embodiment, the first or second tooth entrances 6 and / or the respective second tooth entrances 7 extend beyond or below this contact surface 10, in the setting position. at the time T1, as visible in FIG. 6.
