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 is described for protecting a silver surface against tarnishing. This involves depositing a layer of a silver-copper alloy on a substrate, which may be a silver substrate. The alloy comprises between 0.1 wt % and 10 wt % of copper relative to the total weight of the alloy. At least one layer of a metal oxide or a nitride having a thickness in a range of 1 nm to 200 nm is deposited on the alloy to protect against tarnishing. The presence of copper in the silver-copper alloy enhances the alloy's adhesion without altering the silver color.

An item including a substrate and a coating having a colour with an interference effect for the decoration and/or the protection of the item, the coating including: a first opaque layer covering at least partially at least one surface of the substrate; a stack of at least two semi-transparent layers deposited by an ALD method covering the first layer; the stack having a thickness depending on the colour with an interference phenomenon of the coating.

The invention relates to an article of jewelry comprising a transparent wall which forms a housing provided to receive a precious or semi-precious stone which is immersed and movable in a substantially transparent liquid in the housing and at least one piece which is movable in the liquid and which has the same refractive index as the liquid, the piece immersed in the liquid being substantially optically indiscernible. The housing is delimited by two walls the internal faces of which are preferably mutually parallel, and the stone is inserted into the piece in order to form a movable decorative element, the piece immersed in the liquid being substantially optically indiscernible and comprising an axis of revolution and two guiding surfaces which are adjacent to the internal faces, respectively, and which allow the movable decorative element to move freely in terms of translation and rotation in the liquid about the axis of revolution inside the housing.

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.

An external part component (10) of a watch, of a fashion item or of a jewellery item, including a substrate (11) made of a transparent material, the substrate (11) including an upper face (110) opposite to a lower face (111), the external part component (10) including a base layer (12) deposited over a first portion (1101) of the upper face (110) and at least one secondary layer (13) deposited over the base layer (12) and over a second portion (1102) of the upper face (110), the first and second portions (1101, 1102) of the upper face (110) having different surface conditions.

A timepiece component decoration method includes a base formation step of forming a pattern shape on a base material of a timepiece component and using the pattern shape as a base, a first light-transmissive layer formation step of forming, on a surface of the base, a first light-transmissive layer using a light-transmissive resin, a first liquid repellent treatment step of performing a liquid repellent treatment on a surface of the first light-transmissive layer, and a first printed layer formation step of, to form a first printed layer, ejecting ink and printing a pattern shape by an inkjet method on the surface of the first light-transmissive layer on which the liquid repellent treatment was performed, after the first liquid repellent treatment step.

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 is a watch including a watch case, a cover glass attached to the watch case, and a decorative body attached to the watch case, wherein the watch case includes a holding wall portion provided along an outer periphery of the cover glass, a first column portion provided outside the holding wall portion, a second column portion provided outside the holding wall portion, and provided at a distance from the first column portion, and an inclined portion including an inner end portion formed from between the first and second column portions to the holding wall portion, and is connected with the holding wall portion, and an outer end portion is connected with an outer surface of the watch case and provided at a position close to a rear surface of the watch case, and the decorative body is held by the holding wall portion, the first, and second column portions.

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.
