Abstract: 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.

Abstract: A timepiece includes a mechanical movement with a mechanical oscillator and an electronic device for regulating the medium frequency of this mechanical oscillator. It includes an electromagnetic transducer and an electric converter which includes a power supply capacitor for powering the regulation circuit. The electromagnetic transducer is arranged to supply a voltage signal exhibiting first voltage lobes in first half-alternations and second voltage lobes in second half-alternations of the oscillations of the mechanical oscillator. The regulating device includes a load pump arranged to store momentarily electric loads which are extracted selectively in different time zones according to a time drift detected in the functioning of the mechanical oscillator relative to an auxiliary oscillator, particularly quartz-based. The electric loads extracted are rendered after a certain delay to the power supply capacitor also according to the time drift detected.

Abstract: A winding device includes a motor for driving a watch holder carrying at least one automatic watch with a mobile oscillating mass, and a multimeter for measuring a variation in a resistive torque opposed to the motor by the watch holder equipped with watches, depending on a degree of winding of the watches. The multimeter includes a speed meter to determine a speed and/or a variation in the speed of the motor, a torque meter to determine a value of a torque and/or a variation in the torque at the watch holder, and/or a current meter to determine a value of a current and/or a variation in the current of an electric motor.

Abstract: A balance for timepieces includes a rim, a hub, and at least one arm connecting the hub to the rim. At least one portion of the balance is made of an at least partially amorphous metal alloy. The at least partially amorphous metal alloy is based on an element chosen from the group consisting of platinum, zirconium and titanium, and has a coefficient of thermal expansion comprised between 7 ppm/° C. and 12 ppm/° C. The balance can be manufactured by moulding. A resonator can include such a balance and a monocrystalline quartz balance spring.

Abstract: A device is for fastening a back on a middle of a watch. The back has a shoulder forming a cover arranged to cover entirely partly with the middle and a body arranged to rest in the middle. The device includes at least one pin integral with the middle, a seal mounted between the back and the middle. The back includes, near its periphery, at least one groove, the pin being arranged to slide in the groove between a first position, called the insertion position in which the back is free, and a second position called locking position in which the back is locked and positioned angularly relative to the middle. The groove includes at least one bump to form a hard point and increase the torque when the pin passes through the bump.

Abstract: A layer of lanthanum boride of stoichiometry LaBx where x is between 9 and 12 is deposited on substrate, for example a stainless steel watch dial, and subsequently treated with a laser, such that the portion(s) of the layer treated with the laser change colour according to the laser power. This produces multicoloured surfaces having high resistance to corrosion and abrasion. The layer of LaBx is deposited by PVD and by cathode sputtering, using a LaB6 target of purple-violet colour, such that the colour of the deposited layer differs from the colour of the target. The laser treatment at specific powers changes the stoichiometry of the layer in the treatment portions, such that the colour of these portions changes according to the stoichiometry obtained. At higher powers, the laser will remove the layer of LaBx. Thus the colour of the treated portions is determined by the material of the substrate.
