A motor group including motor modules, each including a motor device driving a display wheel set, with a centre pipe fixed on a plate, including a device for rotational guiding, about a main axis, of a display wheel set internal or external to the centre pipe, this module includes an axial stop arranged to limit to a predetermined value the axial play in the direction of the main axis between the centre pipe and the display wheel set, wherein a protruding surface of the centre pipe or of the display wheel set, or an added axial stop, captively mounted between the centre pipe and the display wheel set, or fixed to the display wheel set.

A system adjusts the angular position of a first toothed wheel set relative to a support on which the first toothed wheel set is mounted such that it can pivot. The adjusting system includes an adjusting member allowing an action to be applied to an angular position of the first toothed wheel set to adjust the angular position of the first toothed wheel set relative to the support. The invention adjusting system can be incorporated into a timepiece.

A device for assembly and alignment on a first bridge, particularly a timepiece movement plate, arranged in a first plane, the device including a second bridge arranged in a second plane, the second bridge being intended to carry a component, in particular a moving component of a timepiece resonator mechanism, the device including a device for aligning the second bridge on the first bridge, the alignment device including at least two bearing faces of the second bridge arranged orthogonally to the second plane in two different directions, the alignment device further including at least two movable adjustment pieces connected to the first bridge, the adjustment pieces each being configured to contact with one of the bearing faces to position the second bridge in a position on the first bridge, the movable pieces defining a plurality of positions of the second bridge on the first bridge.

A positioning mechanism for a toothed wheel mounted on a rotatable staff in a watch movement, the positioning mechanism including a positioning lever exhibiting a flat lateral edge configured to cooperate with at least one flat provided on the staff of the toothed wheel. The positioning lever includes a pivot arm mounted in a pivotable manner about a pivot pin provided in the watch movement, a positioning element exhibiting the flat lateral edge and mounted in an articulated manner on the pivot arm, and a mechanism adjusting and locking the position of the positioning element on the pivot arm in relation to the staff of the toothed wheel.

A mechanical watch movement includes a striking mechanism with a first cannon equipped with a first cannon pinion having at least one snail intended to cooperate with a sensor device of the striking mechanism. The watch also includes a second cannon equipped with a second cannon pinion and carrying the minute hand. The first cannon pinion engages with a going train of the movement and a minute wheel. The minute wheel engages with the first cannon pinion. A motion-work pinion engages with an hour wheel coaxial with the second cannon. The minute wheel is mounted on a lever arranged to pivot about a fixed point. An angular position of the lever may be adjusted by pivoting in such a way as to permit regulation of the position of the minute wheel with respect to the first cannon pinion and to the second cannon pinion.
