A method for manufacturing a pivot bearing () for the pivoting of a timepiece component (), in particular a pivot stone, includes:—boring (E) a hole () in a bearing blank () along an axis (A) intended for the pivoting of a timepiece component (), this hole () forming a start point () of a first pivot zone () of the bearing (), then—laser engraving (E), in the blank (), in particular using a femtosecond laser, a second clearance zone () of the bearing (), juxtaposed with the start point () of a first pivot zone (), this second clearance zone () of the bearing () opening at a first face () of the bearing () blank (), then—removing material by wear (E), in particular by olive-cutting, at the start point () of the first pivot zone () of the bearing () and a boundary zone () between the start point () and the second clearance zone () of the bearing () in order to form a first pivot zone () and a second clearance zone () that are juxtaposed, connected to each other by a rounded connection.

Method for producing a surface of revolution of a clock or watch component comprising a step of machining, with a femtosecond laser beam, a first surface of the clock or watch component so as to obtain a second surface, in particular so as to obtain a second surface whose roughness Ra is less than 100 nm, or less than 70 nm, and then a tribofinishing step applied to the second surface so as to obtain the surface of revolution.

A horology component () for a timepiece, including a first portion () and a second portion (), the first portion () comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (), this second portion () taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion () to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion () is backlit by an emission light wave emitted by the second portion ().

Versatile horology component

A mechanical connection device, in particular a mechanical connection device for a timepiece or a mechanical transmission device for a timepiece, includes a first part having a first area with at least a first micro-cavity; and a second part having a second area with at least a second micro-cavity, the first and second areas being in contact with one another in a mechanical connection configuration.

A process for decorating a timepiece component, which includes performing (i) engraving (E) of a surface to be decorated of the timepiece component with a femtosecond laser; and (ii) structuring (E) of said surface to be decorated of the timepiece component, these two decorations being at least partially superposed on each other.

The invention relates to a method comprising a step (E) of forming a body provided with a cavity on a face of said body, a treatment step (E) consisting of forming, on said body, at least one reinforced adhesion area which is at least partially outside the cavity, and a step (E) of depositing composite material. During the deposition step (E), the cavity is filled and the reinforced adhesion area is covered with the composite material.

A process for decorating a dial includes a step (E) of engraving a pattern in a pad-printing clich&#xe9; with a femtosecond laser, then a step (E) of transferring said pattern to the dial using the pad-printing clich&#xe9;. The process can include surface structuring of the dial, then transferring the pattern to the dial at least partially superposed on surface-structuring obtained by the surface structuring, and can also include an intermediate coloring of the decorated or to be decorated surface in the surface structuring, using a different color from the color used in the transferring.
