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

Abstract: A method for manufacturing a timepiece element, such as an applique, to be mounted on a timepiece component, such as a dial of a timepiece, includes producing a blank of the timepiece element from an injection overmoulding of injectable material into a cavity of a mould. The cavity is defined by the association of at least one impression of a first part of the mould with a second part of the mould including an inlet orifice of the cavity for injecting the material into the cavity. The method also includes finishing the timepiece element including applying a coating on the blank of the timepiece element overmoulded on the second part, and withdrawing the finished timepiece element from the second part, which includes breaking an injection point connecting the timepiece element to the second part in preparation for mounting thereof on the timepiece component.

Abstract: A method for producing a three-dimensional element on a timepiece component, in particular on a dial, that includes generating, by means of a control unit, at least one control instruction for a printing device for reproducing a reference digital graphical representation relating to said three-dimensional element, and constructing, by means of the printing device, at least two substantially superimposed or superimposed layers each having at least one particle which is printed on the timepiece component and which forms the three-dimensional element.

Abstract: A dial for a timepiece, preferably a watch, the dial being provided with a relief portion which is made as an assembly of pieces on different levels, juxtaposed on a base, such that the relief portion is formed by the upper surfaces of the pieces. A method for manufacturing the dial with several separate pieces, the upper surfaces of the pieces being subjected to a polishing step and/or possibly an enamelling step. The pieces are then cut along a defined contour and then assembled edge-to-edge on a base, so as to create the relief portion.

Abstract: A method for plasma treating a target surface of a part, including: obtaining the target surface on the part; placing the part in a chamber of a plasma generator; evacuating the chamber to a pressure of between 10-6 and 10 mbar; injecting a suitable gas into the chamber until a pressure in the chamber of between 10-4 and 102 mbar is reached; generating an electric current discharge within the chamber, via an electric generator, in order to generate a plasma; exposing the target surface of the part to the plasma for a predefined period of time depending on the power of the electric current discharge, on the gas injected into the chamber and on the material of the target surface, so as to deteriorate the surface condition of the target surface in order to increase the roughness thereof to make the target surface mat or more mat.

Abstract: A component and method of making the internal parts or movement for a timepiece or piece of jewelry that includes a substrate partially coated with a black layer and decorated with at least one stone, said black layer including carbon nanotubes or aluminum oxide, said substrate being at least devoid of the black layer on the portion facing the stone.

Abstract: A deposition method for forming a three-dimensional object on a watch dial and/or a watch bezel that includes at least supplying at least one support and depositing an adhesion layer, an outline of the object is delimited in order to enable a cavity to be formed by the deposition of a plurality of polymer layers, such that said object is formed by filling said cavity by the deposition of at least one finish layer.

Abstract: 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.

Abstract: 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.

Abstract: 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.
