Ring (1) for mechanically connecting a first horology component (2) to a second horology component (3), the ring having at least one first elastic arm (11) arranged and/or configured in such a way as to press against a first horology component (2); and at least one second elastic arm (12) arranged and/or configured in such a way as to press against a second horology component (3).

A method for manufacturing appliques on a dial for a timepiece.

A cermet and/or ceramic multi-coloured article, and in particular a bezel (1) of a timepiece, produced by a method for compressing at least two materials (2, 3) of distinct colours, the article including a relief decoration (8) of a different colour from the rest of the article, the decoration (8) being produced by laser ablation on one of the materials (3) after compression of the two materials (2, 3).

A method for fabricating a composite component for horology or jewellery including making a base from a first material, with a first visible apparent surface, and a first support surface; a structure from a second ceramic, or sapphire or at least partially amorphous material, with a second apparent surface and a second support surface, including a through bore machined over the entire thickness thereof; at least one insert made of a third material, for each through bore, and arranged to fit together in a complementary manner with this through bore; bonding this base and each structure to each other, with each first support surface and each second complementary support surface bearing against one another; securing each insert with its respective through bore.

A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

A timepiece dial including a base having a first region having a coating film provided at the surface of the base, a second region where laser light is radiated to the first region to remove the coating film, and a third region, in part of the first region, where the coating film is penetrated and the base is dug down, and the surface roughness of the third region is smaller than the surface roughness of the second region.

A method for fabricating a composite timepiece or jewellery component: a base is made in a substrate with an apparent surface remaining visible; each visible apparent surface is mirror polished; each polished apparent surface is coated with a first transparent or coloured semi-transparent layer of a first material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process; a decorative element is affixed and bonded to an external surface of the first layer; the first layer and each decorative element is coated with a second layer of a transparent treatment material in a dry process, or PVD or CVD or ALD process, or lacquering or zapon varnish process.

A process for manufacturing a watch dial including at least one pattern on a visible face of the dial, the process including: a step of designing a support plate including a dial blank, this step including producing several through holes in the thickness of the body of a support plate, the holes delimiting in such a plate the edge of the dial blank, and a step of producing at least one pattern on a visible face of the dial blank during which step the following is performed: an arrangement of this support plate including the external part element in a mould, and a construction of a blank of each pattern on the visible face of the dial blank, as well as a finalisation of the blank of the pattern.

A system for producing at least one three-dimensional element on a visible face of an external part element of a timepiece implementing this process, the system including a mould formed by the reversible assembly of a first part and a second part configured to receive a support plate of the external part element, the mould including at least one cavity formed by associating the first part including at least one impression with the visible face of the external part element, each cavity helping produce a blank of the three-dimensional element from an over-moulding by injecting injectable material onto the visible face, and a device for applying a coating onto the blank over-moulded on the visible face of the external part element helping finalise this blank of the three-dimensional element.

The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.
