The present application describes a laser turning system (1) for producing a timepiece component, the system including a rotary spindle (3) for moving a bar of material (50) and a galvanometric scanner (12) capable of emitting a femtosecond laser beam scanning a generating profile of the component to be machined in the bar of material (50).

In manufacturing of a first electroformed component and a second electroformed component having portions fitted to each other into close contact, after the first electroformed component is formed, the first electroformed component is used as a portion of an electroforming mold to form the second electroformed component. Using the first electroformed component as a portion of the electroforming mold to form the second electroformed component, the shape of the first electroformed component is transferred to the second electroformed component. As a result, multiple types of components differing in shape may be accurately manufactured concurrently in a series of manufacturing steps.

The invention relates to a process for the production of a part provided with an external element, wherein the process comprises the following steps: provide an electrically conductive substrate having an upper surface and a raised pattern on said upper surface, wherein the pattern has an crest deposit an electrically insulating layer onto the upper surface of the substrate around the pattern to a thickness less than or equal to the distance between the crest and the upper surface deposit a metal layer onto the crest of the pattern 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 formed by a recess, the shape of which corresponds to the imprint of the pattern and the base of which interfaces with the metal layer.

A manufacturing method includes a first repeating step of irradiating a base material with a pulse laser, having a spot diameter S, while relatively moving a laser head and the base material in a first direction, moving the laser head by a predetermined pitch width Pin a second direction that intersects the first direction, and repeating irradiation by the pulse laser along the first direction and movement of the laser head in the second direction, and a second repeating step of irradiating the base material with the pulse laser while relatively moving the laser head and the base material in the second direction, moving the laser head by the pitch width in the first direction, and repeating irradiation by the pulse laser along the second direction and movement of the laser head in the first direction, wherein S<P<100 μm.

A component for the internal parts or the movement for a timepiece or a piece of jewellery including a substrate partially coated with a black layer and decorated with at least one stone, the black layer including carbon nanotubes or aluminium oxide, the substrate being at least devoid of the black layer on the portion facing the stone. It also relates to the method for manufacturing this component for the timepiece or the piece of jewellery.

A method for depositing a rare material in a thin layer at the surface of an horological or jewellery external part includes providing a rough part of rare material, shaping the rough part of rare material so that it is adapted to be used as a target part for a PVD method, depositing material of the target part at the surface of a substrate consisting of an horological or jewellery eternal part by a PVD method so as to cover the external part.

A method for decorating a dial includes deeply digging and forming a first groove by repeatedly scanning, in a predetermined scanning direction, a place where laser light is applied to a base material. In the scanning, a depth of the first groove is controlled by the number of irradiation times that the laser light is applied. An area where a depth of the first groove is shallow and an area where a depth of the first groove is deep are present according to the number of irradiation times.

A method of manufacturing a watch component according to the present disclosure is a method of manufacturing a watch component that includes a decorative region at a front surface thereof. The method includes sequentially irradiating the decorative region with laser light to draw, in a superimposed manner, a plurality of decorative patterns constituted by a plurality of lines. At least one of the decorative patterns is constituted by the plurality of lines arranged at intervals in a range of 80% to 200% of a spot diameter of the laser light, at least one of the plurality of lines including a curved portion.

A method of manufacturing a watch component is a method of manufacturing a watch component in which while a laser irradiation unit and a base member made of metal are moved relatively, laser irradiation is performed to decorate the base member, and includes a first step of irradiating the base member with the laser to form a recessed portion in the base member, a second step of irradiating, with the laser, the base member in which the recessed portion is formed at irradiation intensity less than irradiation intensity of the first step, to clean the base member, and a third step of performing surface treatment on the base member after the cleaning.

A method for producing an applique (1; 1′; 1″) for a timepiece dial, the applique (1; 1′; 1″) having at least two distinct portions (10, 20; 10′, 20′; 10″, 20″) made of a first material and a second material, respectively, the first and second materials being different, wherein the method

includes a first phase (E1 to E4; E1′ to E4′) involving forming at least a second blank (20a; 20a′) made of the second material within or at least partially within a first blank (10a; 10a′) made of the first material so as to obtain a blank (1a; 1a′) of the applique for a timepiece dial,

then a second phase of machining (E5, E6; E5′, E6′) each of the two blanks (10a, 20a; 10a′, 20a′), so as to modify the shape and/or the surface state of each of the first and second blanks of the applique blank (1a; 1a′).
