  • the document FR 2,447,571 discloses a pendulum coupled with two coil springs mounted in series to maintain a center of gravity on the balance shaft.
  • the document EP 0 732 635 discloses the manufacture of a micromechanical component manufactured from a monocrystalline silicon plate and then covered with a layer of a material of improved hardness and coefficient of friction.
  • the object of the present invention is to overcome all or part of the disadvantages mentioned above by proposing a double monoblock spiral whose thermo-elastic coefficient can be adjusted and which is obtained by means of a manufacturing process which minimizes assembly difficulties.
