A method for fabricating an external element or a timepiece dial from non-conductive material, by performing or repeating a basic cycle of making a base from a non-conductive, or ceramic, or glass. or sapphire substrate; dry coating the base with a first sacrificial protective metal layer; etching a decoration with an ultrashort pulse laser to a depth at least equal to the local thickness of the first layer; dry coating the decoration and the remaining part of the first layer with a second metal and/or coloured decorative treatment layer; chemically removing each first layer; and before or after chemical removal of each first layer, mechanically levelling on the upper level of the base the compound thus formed.

A display device comprising a display panel (10) and an electroluminescent light source (20), wherein the display panel (10) includes an intermediate layer and a display surface (12), wherein the electroluminescent light source (20) is configured to project light through the intermediate layer to form an information display on the display surface (12), and wherein the intermediate layer comprises one or more layers selected from crystalized calcium carbonate, porcelain, ceramics, china.

Provided is a timepiece including a decorative body that operates stably and intricately. The timepiece includes: a main plate provided with external teeth extending in a circular-arc shape with a central axis O as a center; a rotating plate rotatable around the central axis O with respect to the main plate; a first gear rotatably supported on the rotating plate; a transmission gear train rotatably supported on the rotating plate, meshing with the external teeth and the first gear, and configured to transmit, to the first gear, rotation of the main plate with respect to the rotating plate; and a first front decorative body non-rotatably connected to the first gear and displaceable with respect to the rotating plate.

A cermet and/or ceramic multi-coloured article, and in particular a bezel (1) of a timepiece, produced by a method for compressing at least two materials (2, 3) of distinct colours, the article including a relief decoration (8) of a different colour from the rest of the article, the decoration (8) being produced by laser ablation on one of the materials (3) after compression of the two materials (2, 3).

A back (1) for a watch case (50), the back (1) including a first element (10) arranged so as to be screwed onto the watch case (50), and a second element (20) including an end face bearing a pattern (M), the second element (20) being mounted such that it can move in rotation about an axis (C) passing through the centre of the case (50), wherein the second element (20) has a brake arranged so as to hold same relative to the first element (10) in different angular positions about the rotational axis (C), the brake being disposed between the first and second elements (10, 20).

The present invention concerns a method for obtaining a finished or semi-finished zirconia-based article, the surface of the article having a metallic external appearance and non-zero surface electrical conductivity, wherein the method includes the steps of: taking at least one zirconia article, pre-shaped in its finished or semi-finished form; placing said article in a chamber in which a hydrogen and carbon/nitrogen gas mixture is heated; heating said article and the gas mixture using at least one resistive element traversed by an electric current to obtain dissociation of the hydrogen and carbon/nitrogen based gas molecules and an increase in the temperature of said article; keeping said article in the reactive atmosphere thus created to obtain diffusion of the carbon/nitrogen atoms in the external surface of said article.

The current invention proposes an improved combination of bracelet and wrist watch comprising a band with watch body where each part defines seconds, minutes and hours. The body is unique and pleasing thus making it suitable for everyone's usage.

A timepiece having a face member with a face surface that displays indicia that is representative of a sports player and the associated sports player sports environment; time hands that represent at least a seconds hand that has a rotatable position about a center axis of the face member; an object that is carried by a distal portion of the seconds hand; the face member depicting a net disposed at a predetermined location on the face surface with the object positioned so that it passes through the net as the seconds hand rotates.

A method for laser additive manufacturing of a mechanical part includes providing a laser beam the operation of which will be controlled by a computer into which is introduced a CAD computer file which is cut into one or more strata which, once superimposed, allow to form the structure of the desired mechanical part, disposing a substrate in a manufacturing enclosure wherein an atmosphere of a neutral gas is created, depositing on the substrate at least a first layer of a powder of a first metallic material to be melted, levelling the first layer, subjecting by means of the laser beam the first layer to a selective melting step, if necessary, depositing on the substrate a second layer, levelling the second layer and subjecting this second layer to a step of selective melting, removing the excess material and cleaning the assembly and subjecting the part to finishing operations.

A watch including a dial including a fixed portion superimposed on a portion movable in rotation including a surface on which are arranged areas with visual appearances different from each other, the fixed portion including at least one through opening emerging on at least one of the areas, the movable portion being kinematically connected to a control member so as to be rotated by actuating the control member and being configured so that when it is rotated, the areas of different visual appearance appear successively through the opening.
