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 fitting (20) for holding a flat component (1), including radial support stops (2; 3), and a chamber (40) bordered by jaws (21; 22) including clamping surfaces (310; 320) for holding the component (1), open on one side by a recess (41; 42) to perform an operation on the component (1), this fitting (20) is deformable between an open position and a closed position around the component (1) tightened by said jaws (21; 22) subjected to a closing force exerted by manoeuvring means arranged to bring these jaws (21; 22) closer to each other.

A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

A method for manufacturing a timepiece component including successive steps of: providing a timepiece component (1); breaking the timepiece component (1) into a plurality of pieces (10); depositing the pieces (10) on a support (2) and creating a desired pattern to be reassembled, the pattern having interstices (1) between the various pieces (10) of the timepiece component (1); transferring the support (2) into a mould adapted by hot forming and placing a preform (3) on the pieces (10) of the timepiece component; heating the whole to a temperature higher than the vitreous transition temperature of the preform (3) and applying a force on the preform to fill the interstices (11) and obtain a reassembled timepiece component (1); cooling the whole below the vitreous transition temperature of the preform (3) to form the reassembled timepiece component (1); recovering the reassembled timepiece component (1) and machining it to the required dimensions.

A method for manufacturing a timepiece component. The method includes: providing a timepiece component (1); breaking the timepiece component (1) into a plurality of pieces (10); and depositing the pieces (10) on a support (2) and creating a desired pattern to be reassembled having interstices (1). The support (2) is then transferred into a mould and a preform (3) is placed on the pieces (10). The assembly is then heated to a temperature higher than the vitreous transition temperature of the preform (3) and a force is applied on the preform to fill the interstices (11) and obtain a reassembled timepiece component (1). The assembly is then cooled below the vitreous transition temperature of the preform (3) to form the reassembled timepiece component (1) whereupon the timepiece component (1) is machined to the required dimensions.

At least one resurfacing system and at least one adjustment guide system for positioning a chuck holding a watch component relative to the resurfacing system. In example embodiments, the adjustment guide system includes one guide rail providing linear offset/distance and angular adjustment and guidance, or two perpendicular guide rails providing linear offset/distance and lateral position adjustment and guidance. Some embodiments include first and second resurfacing systems and a common rotary drive system that drives both the first and second resurfacing systems. The first resurfacing system can be a linear belt resurfacing system and the second resurfacing system can be a rotary disc resurfacing system. Some embodiments including the rotary disc resurfacing system have a metal rotary mounting disc driven by the drive system and a replaceable magnetic resurfacing disc that magnetically adheres to the rotary disc. Also disclosed is a method of resurfacing watches using these watch resurfacing devices.
