A timepiece display mechanism includes at least one display having a shaft, and having at least one plate and/or a bridge carrying at least one guide device for carrying and guiding this shaft around an axis, including, on a first side of said axis, a support surface comprising a V-shape or a pad, symmetrical with respect to a bisector plane passing through the axis, to centre the axis of the shaft on this bisector plane, and on a second opposite side, at least one holding element substantially diametrically opposite the support surface, all the holding elements exerting on this shaft a resultant elastic return force directed towards the axis, and preventing any radial exit of this shaft out of the guide bearing which is a platform with two parallel faces.

Timepiece display mechanism

A horological mobile component, including around an axis, a first element including a first shoulder and a second element including a second shoulder which cooperates by friction with a third shoulder that is included by a third element interposed between the first element and the second element, this third element includes a fourth shoulder cooperating by friction with the first shoulder or being driven onto this first shoulder, and the diameter of the third shoulder is at least double the diameter of the fourth shoulder, and the second element includes a main hollow defining at least two bearing surfaces each including one or two bearing sectors belonging to the second shoulder.

Horological mobile component with element maintained by friction

A horological movement with automatic winding, including a plate, a barrel, a cannon-pinion including a minute pipe which supports a minute hand, an hour wheel set including an hour pipe which supports an hour hand, an oscillating weight, arranged on the same side of the plate as the cannon-pinion and the hour wheel set, which includes a central hub, a rim, a heavy sector, a lifting arbor rigidly connected to the central hub and about which the minute pipe and the hour pipe are mounted coaxially, the minute hand and the hour hand being located between the plate and the rim of the rotor.

Wristwatch

Timepiece barrel with a drum coaxial to a barrel arbour in a direction arranged to confine a barrel spring hooked to the drum and to a core coaxial to the barrel arbour and guided thereon. The core pivots in a bore of the drum, and includes a first stopping surface limiting the axial travel of the core, in the direction, relative to an inner face of the drum, and a second stopping surface opposite the first and limiting the axial travel of the core, relative to an outer face of the drum, which is arranged, on the one hand, imprisoned between the first stopping surface and the second stopping surface, and on the other hand to pivot freely about the core.

Economical timepiece barrel

The movement () includes at least one display ring () which is rotatably mounted on a bottom plate () and which carries markings that will appear in a display zone (). The ring () is fitted with an inner peripheral toothing () which cooperates with drive means () and which cooperates with a jumper spring (). The jumper spring () is drawn towards the radial abutment position by an elastic return element (). A holding plate () is secured on the bottom plate () so as to retain the jumper spring () axially. The holding plate () is secured on the bottom plate () by a bayonet type assembly. The holding plate () includes at least one winding member () which cooperates with the stop device () during the pivoting of the holding plate () from the non fixed angular position thereof to the fixed angular position thereof, so as to arm the associated elastic return element ().
