A method of manufacturing a clock or watch component (19; 29) includes (i) providing (E11; E21) a wafer (11; 21) having a single slice (12; 22) including a material of the component, notably silicon, diamond, quartz, sapphire or ceramic, optionally first coating the lower surface of the slice (22) with a lower layer (24), (iii) etching (E12 to E14; E22 to E24) the slice (12; 22) starting from its upper surface to form at least one clock or watch component, (iv) revealing (E15; E25) at least one clock or watch component (19; 29), by removing a layer that served as a mask for etching (E15; E25) and (y) optionally releasing (E26) the slice and the at least one etched clock or watch component by removing the lower layer (24).

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 pointer hand for a watchmaking part including a body and a cannon configured to be driven onto a cylindrical arbor, the cannon having an internal diameter that is greater than the diameter of the cylindrical arbor. The cannon includes a flat on its internal diameter that is configured to cooperate with the cylindrical arbor, to elastically deform the cannon on both sides of the flat to fix the hand onto the cylindrical arbor.

A design generation method for a watch part includes the steps of: by an output terminal, transmitting, to a server, watch model information selected by a user and event data including at least a date/time entered by the user; by the server, generating, based on the model information received by the server, model data being component information of the watch part; by the server, generating, based on the event data received by the server, unique data and feature data that are a design element of the watch part; by the server, transmitting, to the output terminal, the model data, the unique data, and the feature data; and by the output terminal, displaying the model data, the unique data, and the feature data on a display unit of the output terminal.

Process for manufacturing a hybrid timepiece component, wherein the following steps are comprised: comprising structuring at least one wafer (14) of a first micromachinable material so as to form at least one through-opening (15) within the wafer (14), said structured wafer (14) being intended to form a first part (4) of the hybrid timepiece; component and depositing a metal by electroforming, so that the metal extends through the through-opening (15) and over the two upper and lower faces of the wafer (14) as a single piece resulting from one and the same electroforming step, the electroformed metal being intended to form a second part (8) of the hybrid timepiece component.

A decorative article has a substrate of which at least part of the surface is configured with Ti or stainless steel; and a coating made of primarily TiC and disposed on the substrate. The coating has at least a first region, and a second region disposed closer to the substrate than the first region. The elastic modulus of the second region is greater than the elastic modulus of the first region.

A pointer including a pointer body formed using a carbon fiber textile sheet having a carbon fiber woven thereinto.

The invention relates to a method for decorating a timepiece component comprising: a) a step of preparation of the timepiece component optionally comprising a first step of depositing a first material on the timepiece component to form a first sub-layer, b) a second step of depositing a second material on the timepiece component obtained in step a) to form a second sub-layer, c) a colouring step comprising the deposition of a third coloured material on the timepiece component obtained in step b) to form a coloured external decorative layer,

According to the invention, at least step b) and step c) are achieved by a physical vapour deposition method.

The method makes it possible to produce a decorated component for a timepiece or piece of jewellery. This component provided with the decoration may be, for example, a watch hand. To produce said component, a base substrate is used and a micromachining operation is performed on or in the base substrate to obtain an upper part of the component, which is provided with the decoration. The decoration is produced through the thickness of the upper part and in a programmed pattern. Thereafter, the upper part is placed on a luminescent or colored substance to obtain the component.

Economical method for manufacturing a timepiece display or hand-fitting component: a casing material is chosen for each visible surface: amorphous metal or nanocrystalline alloy or alloy of gold and/or silver and/or copper and/or rhodium and/or titanium and/or aluminium; a thick, hollow blank of a thickness greater than 20 micrometres is created in a first tool, from the casing material with an initial thickness greater than or equal to 50 micrometres, with an overthickness with respect to each visible surface, with a first cavity for reception of a support structure; an interior material is chosen to make a support structure; the support structure is made and joined to the first cavity; one visible surface remaining visible, is diamond tool machined, removing all or part of the overthickness from the blank.
