A method for fabricating metal decorations on a domed dial made of insulating material, wherein the method includes the steps of forming a photosensitive resin mould by a UV LIGA type process, and electrodepositing a layer of at least one metal starting from the conductive layer to form a block, which substantially reaches the upper surface of the photosensitive resin.

Method for fabricating a metal decoration on a dial and dial obtained by this method

A process for producing a part provided with an external element includes: providing an electrically conductive substrate having an upper surface and a raised pattern with a crest on the upper surface; depositing an electrically insulating layer onto the upper surface around the pattern to a thickness less than or equal to the distance between the crest and the upper surface; depositing a metal layer onto the crest by galvanic growth so that the metal layer partly rests on the insulating layer; dissolving the insulating layer; covering an assembly including the substrate and the metal layer with a mass of a base material of the part to form an imprint; separating the mass and the metal layer from the substrate, the mass then exhibiting an external element formed by a recess, the shape of which corresponds to the imprint and the base of which interfaces with the metal layer.

Process for the production of a timepiece provided with a hollow or raised external element

The invention relates to a process for the production of a part provided with an external element comprising the following steps:

Process for the production of a timepiece provided with a raised external element

A method for assembling a stone on a setting support, the stone being cut to exhibit a table, a crown, a girdle and a pavilion. A substrate with a recess for the stone, the recess forming, between the substrate and the stone, a peripheral free space in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, the peripheral free space including a bottom having a conductive surface. Electroplating, in the peripheral free space, a metal layer in the vicinity of the girdle and of the zones of the crown and of the pavilion contiguous to the girdle, so as to confine the girdle in the metal layer to form, around the girdle, the setting support. The stone and its setting support are released from the substrate.

Method for crimping a stone

A method for assembling a stone on to a mounting includes sinking the stone into an adhesive layer on a substrate and then positioning a setting sheet around the stone above the adhesive layer so as to form a peripheral free space between the setting sheet and the stone, at least at the level of the girdle and of areas of the crown and the pavilion adjacent to the girdle. Then, a metallic layer is deposited in the peripheral free space from the setting sheet, at least at the level of the girdle and of the areas of the crown and the pavilion adjacent to the girdle, such that the metallic layer and the setting sheet form the mounting.

Method for setting a stone

A method for fabrication of a piece including, superposing an electrically insulating layer including a first orifice, an additional layer including a first aperture, an intermediate layer including a first hole, and a base layer surmounted by a base motif, depositing a metal layer, so that at the end of this step, the metal layer forms a shell covering electrically conductive walls of the base motif, of the first orifice, of the first aperture and of the first hole, and includes a lateral area resting on the insulating layer, dissolving the insulating layer, coating the metal or alloy layer with a volume formed by a base material of the piece, so that the volume conforms to the shapes of the metal layer.

Method for fabrication of a timepiece provided with a multi-level exterior element

A method of decorating an element. This method includes the steps of: taking the element (), the element including anchoring () for improving the securing of the decoration () to the element; making a mask () of the desired thickness of the decorations (), and having at least one opening ('); placing the at least one opening in the mask () against the place to be decorated so as to form at least one mold (); filling the at least one mold with an at least partially amorphous material via hot forming; and removing the mask ().

Three dimensional decoration method

A method of decorating an element. This method includes the following steps: taking the element (), the element including anchoring for improving the securing of the decoration () to the element; making a mask () of the desired thickness of the decorations (), and having at least one opening (); placing the at least one opening in the mask () against the place to be decorated so as to form at least one mould (); filling the at least one mould with an at least partially amorphous material via hot forming; and removing the mask ().

The invention relates to a decorative part () including several stones () and a device (') for securing the stones () in relation to each other. According to the invention, the securing device (&#x2032;) includes a single electrodeposited base (&#x2032;) whose shape matches one part of the stones, thus allowing all the stones () to be attached in relation to each other without any stress, and the girdles () of the stones () are mounted edge-to-edge in relation to each other so that the single base is concealed. The invention also relates to the method for manufacturing a part () of this type.

Invisible set decorative part

The invention relates to an inlaid ceramic decoration () including a ceramic body () that has at least one recess () forming the pattern for a decoration (). According to the invention, said at least one recess is entirely filled by first and second electrically conductive layers () of approximately 50 nm and a metallic galvanic plating () so as to form a ceramic element () inlaid with at least one metallic decoration () with improved visual rendering. The invention also relates to the method of manufacturing the inlaid ceramic element. The invention concerns the field of decorated ceramic parts.

Ceramic element inlaid with at least one metallic decoration

To fabricate an external timepiece element in which there is inserted at least one decoration, the decoration is formed of anterior and posterior parts respectively intended to emerge from the external element and to serve as a mechanism of anchoring the decoration in the external element. A master mold is provided, the master mold including a hollow pattern cavity matching dimensions of the anterior part of the decoration. The decoration is placed in the pattern cavity. The master mold is filled by the galvanic deposition of a metal. The external element obtained is removed from the master mold.

Method for inserting a decoration in an external timepiece element deposited by electroforming and an external element made in accordance with this method

The present invention relates to a method of decorating an element. This method includes the following steps:

Method for securing a decoration () to an external timepiece element () coated with a galvanically deposited metallic layer (). Instead of the decoration (), a dummy part () is temporarily placed in the hole () pierced in the external element (), and the galvanic deposition () is then carried out. After the deposition has been levelled, the dummy part () is removed and the decoration is placed in the hole ().
