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.

A connectable module used in a wearable electronic device is provided. The connectable module includes a first elastic part disposed to exert a specific elastic force against a pressure applied in a side direction, a second elastic part disposed to exert a specific elastic force against a pressure applied in a vertical direction, and a main body connected to the first elastic part and the second elastic part.

The present invention relates to a timepiece component (100) made up of a polymer-based matrix (110) and a reinforcement (120) that consists of at least two different kinds of cut fibres (121, 122), one of which is a polyazole.

A multicolour cermet and/or ceramic article, and in particular a bezel of a timepiece, made by a method for injecting at least two materials of distinct colours, said article comprising a relief decoration of a colour different from the rest of the article, said decoration being made by laser ablation after injection of the two materials.

An ornamental part, for example for a timepiece, jewellery or telephone, in particular a watch case middle, and its manufacturing method, the part at least partly including a hard material having a Vickers hardness greater than 1000 HV, the method including the following main steps: a step of producing a precursor from a mixture of at least one powder material with a binder, a step of injecting the precursor into a mould in order to form a green body, a step of sintering the green body in order to form a body of the future part from the hard material, and a step of depositing a polymer material coating on one face of the part, the deposition being carried out by moulding on the body, in particular by injection into a mould, the coating and the hard material being inseparable.

A method for manufacturing an exterior part for a timepiece or piece of jewelry made of Murano glass is disclosed. The method comprises providing a material formed of glass rods (2), also referred to as glass tubes, arranged side by side; applying a multi-cycle heat treatment to consolidate the material and form a blank; and machining the blank to produce the exterior part. The heat treatment may comprise 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. Also disclosed is an exterior part for a timepiece or piece of jewelry, in particular a watch case, having a structure with few or no air bubbles.

The manufacturing method comprises at least one processing step for a carbon-carbon composite part (100, 200). In a first variant, the method comprises steps for machining and a step for processing the part. In a second variant, the method comprises a crushing step for the part before the processing step and a moulding step after the processing step. Application to manufacturing timepiece components (170, 270).

Portable electronic device capable of processing information, said portable electronic device including a body arranged to be capable of being secured to the user, and at least one electronic assembly for processing information, the body of the portable electronic device being formed by a layer of plastic material which gives the portable electronic device a shape and thickness, characterized in that the portable electronic device includes a first impermeable plastic film which serves as a coating for the layer of plastic material, and a second impermeable plastic film secured to the periphery of the first impermeable plastic film, and in that the electronic assembly for processing information is arranged between the first and second impermeable plastic films.

The invention also concerns a method of manufacturing a portable electronic device.
