  • Publication number: 20200379408
    Abstract: Disclosed is a method including: a) obtaining a substrate extending in a predetermined plane with a first layer parallel to the plane; b) forming a through-hole in the first layer; c) depositing a second layer on the first, the second layer filling the a through-hole to form a bridge of material; d) etching a hairspring in an etching layer made up of the second layer or the substrate, the one of the second layer and the substrate in which the a hairspring is not etched constituting a support, the bridge of material connecting the hairspring to the support perpendicular to the predetermined plane; e) removing the first layer, the hairspring remaining attached to the support by the bridge of material; f) subjecting the hairspring to a thermal treatment; and g) detaching the hairspring from the support.

  • Patent number: 10539926
    Abstract: A balance spring for an oscillator of a timepiece, wherein it comprises a component part, in particular at least a coil or a portion of a coil, provided with heavily doped silicon having an ion density greater than or equal to 1018 at/cm3, in order to permit the thermo-compensation of the oscillator.

  • Publication number: 20190271946
    Abstract: A process for manufacturing a timepiece oscillator made up of a balance and of at least two spring portions that are arranged in parallel, which includes (a) choosing the frequency f of the oscillator, (b) choosing a balance and spring portions so that the inertia of the balance and the angular stiffnesses of the spring portions allow an oscillator of chosen frequency f to be formed and so that the variations in angular stiffness of the spring portions as a function of temperature are able to thermo-compensate the oscillator, and (c) assembling the chosen spring portions with the chosen balance.

  • Patent number: 10338528
    Abstract: The invention relates to a method for fabrication of a balance spring of a predetermined stiffness comprising the steps of fabricating a balance spring in dimensions of increased thickness, determining the stiffness of the balance spring formed in step a) in order to remove, locally, a volume of material, in order to obtain the balance spring having the dimensions necessary for said predetermined stiffness.

  • Patent number: 10324418
    Abstract: The invention relates to a method for fabrication of a balance spring of a predetermined stiffness comprising the steps of fabricating a balance spring in dimensions to obtain a deliberately lower stiffness, determining the stiffness of the balance spring formed in step a) in order to compensate for said missing thickness of material required to obtain the balance spring having the dimensions necessary for said predetermined stiffness.

  • Patent number: 10120341
    Abstract: A method for determining an imbalance characteristic of a hairspring (5) balance (4) oscillator (3) of a timepiece movement (2), the method comprising at least the following steps: —Setting the hairspring balance oscillator in an oscillating motion at at least two amplitudes, —Determining, for each amplitude and for at least two positions of the oscillator, a piece of data representative of the oscillation period of the oscillator, —Using the data from the previous step to calculate the imbalance characteristic of the hairspring balance oscillator.
