A method for decorating the surface of a mechanical part including structuring, on the surface to be decorated, a masking layer having a thickness that is at least equal to the thickness of the decoration element to be produced; making, in the masking layer, at least one opening that coincides with the location on the surface to be decorated where the decoration element is to be produced, the opening having a contour that is identical to the contour of the decoration element and defining a volume with the mechanical part; filling the volume delimited by the masking layer and the surface to be decorated of with a filling material wherein the decoration elements are sought to be produced; and removing the masking layer.

A process for blanking an applique for a watch dial, comprises a step of blanking with a laser beam a first part of the outline of this applique, defining a pointed zone or/and a thin groove of at least a first hollow or/and the point or/and the drawn-out portion of at least a first projecting part, and a step of blanking by means of a stamp a second part of said outline which is complementary with the first part. This hybrid blanking technology makes it possible to obtain appliques having, at the end of the blanking process according to the invention, an outline which defines at least one hollow having a pointed zone or/and a thin groove or/and which defines at least one projecting part forming a point or/and a drawn-out portion with configurations and particular dimensions that cannot be obtained by blanking merely by stamping.

The invention relates to a watch having a variable dial, and more specifically a watch that provides the wearer with the possibility of partially changing the appearance of the dial. According to the invention, the watch has a dial (1) that has at least one opening (6, 7) occupied by a removable bezel (3, 5) and the watch further has a plurality of carrying arms (9, 10) disposed radially on a carousel (8), each arm end situated on the circumference carrying a bezel (3, 5) and the carousel (8) being able to rotate about an axis perpendicular to the plane of the dial (1) and passing through the center thereof.

The invention relates to a method for bonding timepiece components, comprising applying an adhesive to a first and/or second timepiece component to be bonded to one another, and depositing an adhesion layer onto at least one of the first and second components to be bonded by spraying a primer composition in a localised joining area followed by the solidification of the primer composition. The adhesion layer is deposited prior to the application of the adhesive if the adhesive is applied to the one or more same components as the adhesion layer.

A process for producing a part provided with an external element includes: providing an electrically conductive substrate having an upper surface and a raised pattern with a crest on the upper surface; depositing an electrically insulating layer onto the upper surface around the pattern to a thickness less than or equal to the distance between the crest and the upper surface; depositing a metal layer onto the crest by galvanic growth so that the metal layer partly rests on the insulating layer; dissolving the insulating layer; covering an assembly including the substrate and the metal layer with a mass of a base material of the part to form an imprint; separating the mass and the metal layer from the substrate, the mass then exhibiting an external element formed by a recess, the shape of which corresponds to the imprint and the base of which interfaces with the metal layer.
