Abstract: A process for decorating a timepiece component, which includes performing (i) engraving (E10) of a surface to be decorated of the timepiece component with a femtosecond laser; and (ii) structuring (E20) of said surface to be decorated of the timepiece component, these two decorations being at least partially superposed on each other.
Abstract: A micromechanical timepiece part includes a silicon-based substrate having at least one surface, at least one part of the surface having pores which open out at the external surface of the micromechanical timepiece part and the pores include a tribological agent. A method for producing a micromechanical timepiece part starting from a silicon-based substrate, the silicon-based substrate having at least one surface, at least one part of which is lubricated by a tribological agent, the method includes the steps of forming pores on the surface of the part of the surface of the silicon-based substrate, and depositing the tribological agent in the pores.
Abstract: A method of forming a decorative surface on a micromechanical timepiece part including a silicon-based substrate, including at least one step a) of forming pores (2) on the surface of the silicon-based substrate over a zone of the silicon-based substrate which corresponds to the decorative surface to be formed, the pores being designed to open out at the external surface of the micromechanical timepiece part. A micromechanical timepiece part including a silicon-based substrate, and having, over at least one zone of the silicon-based substrate, pores which are formed in the zone of the silicon-based substrate and open out at the external surface of the micromechanical timepiece part in order to form a decorative surface over the zone.
Abstract: Device for securing and locking a display element (1) mounted on a support (3) using at least one assembly element (2) in a direction of assembly (D). The device includes at least one locking element (4) for the assembly element (2) and the locking element (4) is accessible from the visible side (11) of the display element (1).
Abstract: A case unit includes a resin case main body including an outer peripheral surface and an opening forming surface enclosed by the outer peripheral surface and being formed with an opening. A step is provided on an inner peripheral surface of the opening to face an entrance of the opening. An elastic member is provided along the inner peripheral surface of the opening and mounted on the step. A light transmission member is press-fitted in the opening via the elastic member and covers the opening. And, a fitting part of a frame member is fitted on the outer peripheral surface of the resin case main body to make an elastic member pressing part extending from the fitting part toward the entrance of the frame member cover at least a part of the elastic member at the entrance of the opening.
Abstract: Systems and methods for a dual illumination watch face having a tritium gas tube coupled with a dial, minute hand or hour hand of the watch face, and phosphorescent material disposed with at least one of the dial, minute hand and hour hand.
Abstract: The surface of metallic appearance of the timepiece dial has a visible morphology corresponding to that of mother-of-pearl. According to the process for manufacturing this dial, a mother-of-pearl sheet is subjected to a sandblasting operation, to give its surface finish the morphology of mother-of-pearl, this surface is cleaned and coated with a layer of metallic appearance.

Abstract: The method consists, from a profile having a section corresponding either to the envelope of the base of the symbol or to that of its section, in first of all machining the feet, transferring the preformed profile in a clamp, gripping the symbol by the feet, cutting the preform, shaping and diamondpolishing all of the visible faces of said symbol, and transferring said finished symbol into an individual packing tray using a robot.
Abstract: The present invention, in at least one embodiment, concerns a process for the multiple marking out of stone seating on a setting surface, in particular on a watchcase middle, and a kit for using at least one embodiment of the invention in a multiple marking-out process.
Abstract: The invention concerns a method of setting a plurality of stones each having a culasse, a crown and a girdle in a metal support element including the steps of: milling a groove on a first face of the support element; piercing from a second face of the support element, opposite to said first face, a plurality of holes each having a diameter substantially corresponding to the diameter of the girdle of the stone that it will receive, such that each hole opens into said groove and the bottom of each hole forms a support wall for the crown of the stone; forming grains in the second face of the support element in proximity to the support walls; setting the stones in place in the holes such that the crown of each stone abuts against the support wall of the hole thereof; and pushing the grains against the culasse of each stone in order to fix the stones in said support element.

Abstract: In order to manufacture the display element intended for a timepiece, a sheet of plastic material shaped in a tape (3) is provided. The sheet is then deformed using tools (4, 6) by thermoforming to give it a profile (10, 11, 13, B) corresponding to the outer contour (20) of said elements. Such an element can be a date disc or a dial.
