A horology component based on a fragile material, wherein said component comprises at least one surface part of fragile material covered with a coating (10) comprising at least two layers CE of elastic material (11) separated by a layer CR of a material (12) stronger than the elastic material (11).

A display mechanism of a watch including at least one indicator member and a drive member assembly. The indicator member is mounted to rotate about a first axis of rotation and is configured to indicate a time. The indicator member also has a second axis of rotation extending along the indicator member and a rotary element mounted to rotate about the second axis of rotation. The drive assembly includes a first drive member and a second drive member such that the first drive member drives the rotary element when it is moving about the first axis of rotation.

A watch component includes a base material, and a decorative film including a color absorption film and a color adjustment film, an arithmetic mean roughness Ra of a surface, on which the decorative film is disposed, of the base materialis equal to or greater than 0.02 m and equal to or less than 0.1 m, a film thickness of the decorative film is equal to or greater than 0.25 m and equal to or less than 1.0 m, and a ratio of the film thickness of the decorative film to the arithmetic mean roughness Ra of the surface is equal to or greater than 2.5 and equal to or less than 25.

A timepiece hand and method for manufacturing same, including: obtaining a single-piece part, the part extending along a longitudinal axis; rotating the single-piece part; emitting a first modulation of the laser light; exposing a first portion of the single-piece part to the first modulation of the laser light to form a first volume with a circular cross-section with a length L.sub.1 and with a mean diameter D.sub.1, the ratio

[00001]$\frac{L_1}{D_1}$

being less than or equal to 20 or 10; emitting a second modulation of the laser light; and exposing a second portion of the single-piece part to the second modulation of the laser light, to form a second volume with a circular cross-section with a length L.sub.2 and with a mean diameter D.sub.2, the ratio

[00002]$\frac{L_2}{D_2}$

An actuation mechanism (60) of a flexible hand (44) to which a clockwork movement applies a first angular rotation (1), the flexible hand (44) including a first drive barrel (46) and a second drive barrel (50) connected to a tip (54) of the flexible hand (44) by a first and a second flexible arm (48), the first drive barrel (46) being provided with a first toothing (56) and the second drive barrel (50) being provided with a second toothing (58), the first and second drive barrels (46, 50) being mounted so the first toothing (56) of the first drive barrel (46) engages with the second toothing (58) of the second drive barrel (50) in the stressed position of the flexible hand (44), the angular rotation (1) applied by the clockwork movement to the actuation mechanism (60) being modulated by an angle of rotation () by the actuation mechanism (60).

A method for manufacturing a luminescent hand for a horological movement, preferably for a watch. The method includes providing a support comprising a light guide and structuring an emergent surface of the light guide so as to extract a maximum amount of light from the luminescent hand. The luminescent hand includes, over a lower face, a layer of luminescent material including one or more deposit(s) of fluorescent material, opposite a light source. The light source is laced at locations close to the axis of rotation or away from the axis of rotation but at a distance from the luminescent material. Thus, the light source is not placed on the luminescent hand.

A timepiece display mechanism with an instantaneous jump function, including a Maltese cross mechanism with an annular ring controlling, in part of its travel, the pivoting of a planet wheel set and driven by a timepiece movement via a cam wheel set arranged to move the annular ring from an activated position to a deactivated position in an instantaneous displacement in order to pivot a planet wheel set, and vice versa in a controlled return slower than the instantaneous displacement, the cam wheel set includes a coaxial cam and plate including a slot for driving an eccentric finger of the cam which controls the pivoting of a driver driving the annular ring between two extreme activation and deactivation positions, the slot allowing a clear jump of the driver in the deactivation position, and a longer reactivation time.
