Abstract:
The timepiece movement is provided with an analog display device for an item of information whose value varies periodically or intermittently, this analog display device including an indicator for said information provided with a toothing and a mechanism for the periodic or intermittent driving of the indicator, this mechanism comprising a rotating wheel set whose pinion, in a meshing relationship with the toothing, is formed of two pins which are diametrically opposite relative to the rotational axis of the rotating wheel set, these two pins being configured to alternately penetrate successive hollows in the toothing and to form a self-locking system when the timepiece movement is subjected to shocks. Each of the two pins has, in a general plane of the toothing perpendicular to the axis of rotation of the rotating wheel set, a transverse profile having a first outer portion substantially in the arc of a circle centered on the axis of rotation.
