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 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 watch dial includes a substrate, a protruding portion formed on the substrate by laser machining, and a coating layer provided around the protruding portion. At least a portion of an upper surface of the protruding portion is exposed from the coating layer.

Provided are a printing jig for an inkjet-type printer and a method for manufacturing printed objects therewith, which jig can be easily produced in accordance with the shape and size of an object to be printed and allows the object to be accurately positioned relative to the printer. The printing jig supports an object to be printed, and is placed in an inkjet-type printer when the object is being printed. The printing jig includes a mounting surface on which the object is to be placed, and a positioning part for positioning the object. The positioning part includes a protrusion preformed on the mounting surface so as to be brought into contact with at least part of the object placed on the mounting surface. The protrusion is made of deposited and cured ink used by the inkjet-type printer.

The present invention relates to a method for manufacturing an exterior part for a timepiece or piece of jewelry made of Murano glass, said method comprising the following steps: providing a material formed of glass rods (2), also referred to as glass tubes, arranged side by side; multi-cycle heat treatment to consolidate the material and form a blank; machining the blank to produce the exterior part, the method being characterised in that the heat treatment comprises a first cycle (a) consisting of heating the material from a temperature less than or equal to 100° C. to a temperature between 450 and 650° C. at a heating rate between 4 and 12° C./min in order to avoid the formation of air bubbles during the manufacturing of the blank. It also relates to the exterior part for a timepiece or piece of jewelry, in particular a watch case, having a structure with few or no air bubbles.

A system for fastening and/or extracting a dial disposed on a support. The dial includes a holding portion configured to bring the dial against the support and an extracting portion configured to move the dial away from the support. The system includes a movable organ configured to displace or be displaced between a fastening position and an extraction position. The movable organ includes a holding surface configured to cooperate with the holding portion so as to bring the dial against the support and an extraction surface configured to cooperate with the extraction portion so as to move the dial away from the support.

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′).

A dial decoration method of the present disclosure is a dial decoration method including a base formation step of forming a pattern shape on a base material and using the pattern shape as a base, and a printed layer formation step of forming a printed layer on a surface side of the base, and the printed layer formation step includes printing a pattern shape, to form the printed layer, by changing a density of dots of ink ejected by an inkjet method.

A method for manufacturing an applique including an upper surface and a rim intended to be seen by a user, a lower surface for its resting on a dial or a structure of a timepiece and at least one foot protruding from the lower surface, the method making it possible to obtain a varnished applique.

A watch component includes a base material including a first region having a surface at which a plurality of recessed portions are formed and a second region having a smooth surface, and a multilayer film configured to cover at least a portion of the base material. When viewed in a cross-sectional view taken along a thickness direction of the base material, the plurality of recessed portions are defined by a first side and a second side that is tilted with respect to the first side and is in contact with the first side at an end portion, and a hue angle of the first region is greater than a hue angle of the second region.
