Disclosed is a method for manufacturing a horological component according to which a silicon-based piece having the desired shape of the horological component is produced and the piece is subjected to a thermal oxidation and deoxidation treatment to remove a predetermined thickness of silicon in order to increase the mechanical strength of the piece. This method is characterized in that the thermal oxidation and deoxidation treatment is carried out in several steps, each step including a thermal oxidation phase followed by a deoxidation phase.

Packaging (1) for clock hands (2) with a pipe (4) and a body (5), including a pallet (10) for receiving, holding, storing and carrying hands (2) having the same height, including bores (11) for receiving the pipes (4) according to a constant pitch, adjacent to recesses (12) for housing the hand bodies (5) resting on an upper surface (13), each pallet (10) including a position index device (20), and a spacer (15) for cooperating such that it bears against a lower surface (14) of another pallet (10) and extending, from the upper surface (13), over a height which exceeds that of the hand bodies (5), each pallet (10) having a transverse bearing surface (130) for receiving the bearing surfaces (3) of the hands (2), and, parallel thereto, oblong pieces (131), the width whereof is adapted for the insertion of robotic grippers or tweezers for loading/unloading hands.

Types of metal component parts including a casing, a bezel, a buckle, parts for a watch band, etc. are made with the Metal Injection Molding (MIM) process. Each type of metal component part can be derived from an instance of a MIM blank corresponding to that particular type of metal component part formed from its corresponding injection molding tool. The MIM blank formed for the metal component part from the injection molding tool then has a portion of the MIM blank subtracted through a laser subtraction process to form an interim shape and geometry of the instance of the metal component part. The laser subtraction process is applied to the instance of the MIM blank for the metal component part when the instance of the MIM blank has not yet been sintered and hardened to a finished shape and geometry for that metal component part for the watch design.

A method is for manufacturing a stone, in particular for a timepiece, from a mineral body of monocrystalline or polycrystalline type. The method includes an ablation step in which the body is subjected to a material ablation by scanning on at least one face of the body using ultra-short pulse laser radiation whose duration is less than one hundred picoseconds, and whose beam is guided by a precession system having at least three axes to at least partially cancel the angle of the laser cone, which is due to the focusing of the laser. A mineral stone of monocrystalline or polycrystalline type, in particular for a horological movement, is likely to be obtained by the method. The stone includes in particular a face provided with a peripheral rim, in particular for laterally clamping an endstone in a bearing.

The invention relates to a wristwatch with a clock generator assembly. The clock generator assembly comprises a first clock generator, a pulse counter, and an output device. The first clock generator comprises a piezoelectric oscillating crystal and is configured to generate a clock signal. The pulse counter is configured to count the clock signal of the first clock generator, wherein the output device is configured to output a useful signal if a count value of the counted clock signal of the first clock generator is equal to a predetermined count value.

A method for manufacturing at least a part of a timepiece is disclosed. The method comprises a first step of assembling flat layers together to from a substantially flat multilayer structure, Wherein at least a first layer of said layers is designed to form one flexible blade in the timepiece. Then, the multilayer structure is deployed in a direction substantially normal to the flat layers. Then at least one mass is fixed to the flexible blade, the mass being more rigid than the flexible blade.

A method for disassembling first and second watch-surfaces of a watch includes the steps of removing a decorative cover from the watch; rotating an adjusting screw to move an H-shaped snapping member toward a casing so that the H-shaped snapping member abuts against the adjusting screw; rotating a snapping ring so that an engaging protrusion does not overlap a pressing protrusion and the snapping ring can be removed from the casing; opening the watch; using a tool to press against a platform of the connecting sleeve; rotating the main screw to remove the connecting sleeve; removing the first watch-surface from the casing; removing first and second positioning rings and suspension columns; turning the casing to remove the snapping ring; opening the watch; using the tool to press against the platform; rotating the main screw to remove the connecting sleeve; and removing the second watch-surface from the casing.

A method for fabricating a composite component for horology or jewellery including making a base from a first material, with a first visible apparent surface, and a first support surface; a structure from a second ceramic, or sapphire or at least partially amorphous material, with a second apparent surface and a second support surface, including a through bore machined over the entire thickness thereof; at least one insert made of a third material, for each through bore, and arranged to fit together in a complementary manner with this through bore; bonding this base and each structure to each other, with each first support surface and each second complementary support surface bearing against one another; securing each insert with its respective through bore.

A method for manufacturing a horological mobile (10) including: depositing a first thin layer (11) with a first material including at least nickel, the periphery of which defines the contour of the geometry of the horological mobile (10); depositing an intermediate layer (12), with a second material including at least nickel and phosphorus, so as to cover a face of the first thin layer (11), the periphery of which corresponds to that of the geometric shape of the first thin layer (11); depositing a second thin layer (13) with the first material, so as to cover a face of the intermediate layer (12), the periphery of which corresponds to that of the geometric shape of the first thin layer (11), wherein the first and the second thin layer (11, 13) are poorer in phosphorus than the intermediate layer (12), or do not contain any phosphorus.
