A method that is for manufacturing a timepiece provided with a personalized decoration, visible in particular when the timepiece is worn, includes constructing the timepiece and producing the personalized decoration on all or part of a body of the timepiece. Producing the personalized decoration includes selecting from a human-machine interface of an electronic device a single portion of a reference digital graphical representation, in particular of an ephemeral reference digital graphic representation, and applying a coating of decorative material on all or part of the body of the timepiece as a function of the descriptive characteristics of the selected single portion.

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 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.

The present disclosure discloses a UV watch screen protector sticking machine, which includes an upper cover component, a base, and a screen protector positioning component. The screen protector positioning component includes a positioning member and a liquid absorbing member. The positioning member is provided with a screen protector mounting hole, a press member, and a removal hole. A UV curing lamp is arranged in the upper cover component, and the base is provided with a placement slot of a fool-proof slot structure, a limiting member, an elastic member, and a locking member. The present disclosure solves the problems in the background section that the existing watch screen protector sticking machine does not have a curing function itself, a glue absorbing material is inconvenient to replace, it is complex to position the watch and apply the screen protector in the sticking process of the screen protector, and the like.

A method for protecting a neodymium-iron-boron watch magnet against corrosion is provided. The method includes a sandblasting treatment of the watch magnet surface following by an ion implantation in an oxygen plasma or a nitrogen plasma to obtain an impervious surface layer with all of the surface bonds saturated by the implanted ions acting as a barrier against oxidation and preventing corrosion of the watch magnet in a humid environment, under the usual conditions for wearing watches.

Component, in particular a timepiece component, which has at least one porous core that includes a first material or based on a first material, having a relative density less than or equal to 80%, or less than or equal to 60%, or less than or equal to 50%, of the relative density of the first material in solid form, the at least one porous core having at least one area for which its porosity at its surface is lower than its porosity away from its surface.

A method for producing a timepiece component, a first part whereof includes a toleranced first reference surface, whereby, in a first step, a first material is chosen to produce this first part by additive manufacturing, and a base is prepared; in a second step, a base surface is etched in the base, which base surface is the negative of the first reference surface, and the base is positioned on an additive manufacturing means; in a third step, the first part of the component is grown by additive manufacturing in contact with the whole of the base surface; in a fourth step, the development of the first part is verified against a predetermined setpoint value, and the third additive manufacturing step is repeated iteratively until the desired level of development has been reached.

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.

A pivot axis for a horology movement, including at least a part made of pure tungsten or of a tungsten alloy with at least a portion of the part converted into a layer of tungsten carbide (5).
