A method for making and decorating top and bottom surfaces of a transparent timepiece component, the method including: depositing a first decoration on a male pattern; moving the male pattern, covered or not covered by a preform, into an injection chamber and injecting a transparent material therein to coat the male pattern to obtain a compound including the top face with the first decoration, on the bottom face; polymerizing the first compound in the injection chamber and then removing therefrom; depositing another material and/or second decoration in a cavity and held by gravity, and deposited on the top surface via a relative motion in the direction of gravity, to obtain a second compound.

Method for making and decorating a transparent timepiece component

Method for forming a transparent timepiece component including top and bottom surfaces: Hardness is improved by the UV exposition of this component.

Method of forming a transparent one piece timepiece component

A method for mechanical and/or optical functionalization of a transparent timepiece component, including: forming a body of methyl polymethacrylate, including a bottom surface and a mechanical and/or optically functionalized intermediate surface; coating the body with a layer made by injecting a second transparent polymerizable material into a cavity between a mold and the body or an intermediate body delimited by a complementary intermediate surface of a contact surface of a preceding mold, the last mold being the negative of the top surface of the component; polymerizing the second material therein; removing the component from the flexible mold by deformation of the mold. Hardness can be improved by UV irradiation of a component.

Method for mechanical and/or optical functionalization of a transparent timepiece component

An electronic timepiece movement including a timepiece motor formed by an assembly comprising a frame made of non-magnetic material and a rotor housed in said frame; and method of manufacturing a motor of this type wherein the frame is first made with a lateral aperture, said frame including a first part and a second part each carrying a bearing, the first part or the first and second parts of the frame being elastically deformable. Next, the rotor is mounted in the frame through the lateral aperture therein by increasing the distance between the two bearings of the frame via the elastic deformation of the first part or of the first and second parts of said frame, said elastic deformation being provided in particular for the insertion of the two rotor pivots into the two respective bearings of the pre-formed frame.

Electromagnetic timepiece motor and method of manufacturing the same

A replacement cartridge (1) for a shaver with an application device has an application preparation reservoir (2) and means for feeding the application preparation such as a small manually operated pump (3), and a connecting piece (10). The replacement cartridge is fixed to the shaver by a coupling between the connecting piece (10) and a counterpart (4). In the new state of the replacement cartridge, the interior of the small pump (31) is filled with application preparation. The integration of the small pump into the replacement cartridge (1) and its initial filling with preparation permits a simple design of the pump. The pump has a pump chamber (31) whose walls have elastically deformable points and two one-way valves (32, 33). A preparation reservoir has a hollow body whose interior is subdivided into a preparation chamber (22) and an air chamber (23) by a movable plunger (21).
