Abstract: The invention relates to a method for manufacturing a composite component of a timepiece or of a jewelry part, the composite component comprising a porous ceramic part and a metallic material filling the pores of said ceramic part, said method comprising the steps of: providing a porous ceramic preform of the component, providing a metallic material, heating the metallic material to a temperature higher than the melting point of the metallic material, filling the pores of the ceramic preform with the molten metallic material, cooling the metallic material and the ceramic preform to obtain a solidified metallic material in the pores of the ceramic preform, and applying finishing treatments to obtain the composite component, wherein said porous ceramic preform consists essentially of a material selected from the group consisting of Si3N4, SiO2 and mixtures thereof, and said metallic material is selected from the group consisting of gold, platinum, palladium metals and alloys of these metals.
The invention relates also to a composite component of a timepiece or of a jewelry part comprising a porous ceramic part and a metallic material filling the pores of said ceramic part, wherein said porous ceramic part consists essentially of a material selected from the group consisting of Si3N4, SO2 and mixtures thereof, and said metallic material which is selected from the group consisting of gold, platinum, palladium metals and alloys of these metals.

Abstract: A modular watch (1) including at least a middle (10), a back (11), a display module (12) having a dial, time display means, a crystal and first magnetic gear means, a horological module (13) including a horological movement with second magnetic gear means arranged to cooperate with the magnetic gear means of the display module (12), and first and second bracelet strands integral with the middle (10) at a pair of horns (20, 30). The display module (12) and the horological module (13) are mounted one on top of the other, said display module (12) being mounted such that it is fixed against the middle (10), and the horological module (13) being mounted such that it can rotate between the back (11) and the display module (12) in order to set the time.

Abstract: A method for manufacturing an austenitic stainless steel workpiece including the following successive steps: 1) providing a powder and sintering the powder to form a sintered alloy with an austenitic structure; the alloy having a nitrogen content greater than or equal to 0.1% by weight, 2) treating the sintered alloy to transform the austenitic structure into a ferritic structure or ferrite+ austenite two-phase structure on a surface layer of the alloy, 3) treating the sintered alloy to transform the ferritic or ferrite+ austenite two-phase structure obtained in step 2) into an austenitic structure and, after cooling, forming the workpiece which, on the layer subjected to the transformations in steps 2) and 3), has a density higher than that of the core of the workpiece. The present description also relates to the workpiece obtained by the method which has a very dense surface layer (≥99%).
