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 manufacturing a horology component comprising a surface that is to be treated, this surface being prepared beforehand through a substep of polishing and/or through a substep of adding a malleable upper layer (2), wherein said method comprise: a first surface structuring (E10) of said surface that is to be treated of the horology component, followed by a second surface structuring (E20) of said surface that is to be treated, structured by the previous first surface structuring step (E10).

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 display panel includes a plate-shaped decoration member including a shading part and a light transmission part formed within the shading part, as well as a plate-shaped reflection member disposed on a back side of the decoration member. The shading part and the light transmission part create a fine pattern in plan view. The reflection member is configured to reflect light. The decoration member is disposed on a front surface of the reflection member.

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.
