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 watch external part of the present invention is equipped with a substrate and a coating formed using an aerosol deposition method. The coating is selectively provided at a portion of a site observable in a state with the watch external part incorporated in a watch. The substrate is made of a material including one type or two or more types selected from a group consisting of sapphire glass, quartz, and plastic. The watch external part is further equipped with a ground layer having at least one layer between the substrate and the coating.

The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate 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 with a shape corresponding to the imprint of the pattern.

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 process for manufacturing a timepiece or jewellery component, the component being manufactured from a first material, the process including: obtaining the component, having undergone, at a very latest during the obtaining, a treatment directed toward combining the component with a chromic element, the chromic element including at least one pigment capable of reacting to an energy supply and a matrix for binding the pigment; placing the component in a machine capable of at least locally supplying energy to the component; using the energy supply machine in a predefined operating program at least locally to provide energy to the chromic element to bring about a reaction of its pigment; removing the component from the energy supply machine.

A spinning device attachable to a band, including a watch and with the spinning device rotatably mounted on a spin-able mount with a bearing and attached to a band, the band receivable onto a user's wrist or finger. The wrist-mounted, or alternatively finger-mounted spinner device includes a watch, mounted in a stationary position, or alternatively in a rotatable position above the spinner device. The spin-able mount includes a spinner bearing attached to a band, the spin-able mount rotatable about the spinner bearing mounted between a post nut and a base screw. The base screw of the spin-able mount receives a bottom band washer and a top band washer, with the top band washer firmly sandwiching the band.

The present invention relates to a timepiece component comprising on at least one part of its surface a coating formed of one or more layers of organic pigments.

A case including a case main body, an operation member having an operation head portion which protrudes outside of the case main body, an exterior member which is detachably attached to the case main body while covering outer periphery of the case main body, in which the case main body has a protection projection provided on an outer peripheral surface such that an outward projection length becomes shorter from an upper side toward a lower side, and the exterior member has a housing portion which houses the protection projection.

A decorative item is made of a ceramic material, where ceramic material includes a carbide phase and an oxide phase, the carbide phase being present in a percentage by volume comprised between 50 and 95% and the oxide phase being present in a percentage by volume comprised between 5 and 50%. The decorative item is manufactured by a method of powder metallurgy.

A method for manufacturing a structured insert (10) for a mold for manufacturing a timepiece or jewelry component, for example a bracelet strand, including: —providing (E1) a template element (50) comprising a structured surface (51) with a pattern to be reproduced on a surface of a timepiece component; —covering (E2) the structured surface (51) of the template element (50) with a molding resin capable of reproducing a negative pattern of the pattern of the structured surface, and leaving the molding resin to solidify in order to obtain a structured insert (10); —separating (E3) the structured insert (10) from the template element (50), the structured insert (10) comprising a surface comprising the negative pattern; —optionally, cutting the structured insert (10) to the format corresponding to at least part of the timepiece component to be manufactured.
