Definitions

  • the invention also relates to a watch movement comprising at least one such oscillator and / or such a resonator mechanism.
  • the invention proposes to better manage the torsional stiffness of the suspension, and consequently to limit the out-of-plane displacement stroke of the blades of a reed-plate resonator, and thus to ensure a better holding of the system.
  • the longitudinal translation table 31 and the transverse translation table 32 each comprise at least two flexible blades or rods, each blade or rod being characterized by its thickness along the second direction X when the blade or rod extends in the third direction Y or vice versa, by its height in the first direction Z, and by its length in the direction in which the blade or rod extends, the length being at least five times greater than the height, the height being at least as large as the thickness, and more particularly at least five times greater than this thickness, and more particularly still at least seven times greater than this thickness.
  • the transverse blades or rods of the transverse translation table 32 have a first plane of symmetry, which is parallel to the transverse axis D2, and which passes through the pivot axis D.
  • the longitudinal translation table 31 comprises at least two blades or flexible longitudinal rods parallel to each other and of the same length.
  • the resonator mechanism 100 comprises axial abutment means comprising at least a first axial abutment 7 and a second axial abutment 8 to limit the translation travel of the inertial element 2 at least in the first direction Z, the means axial abutment being arranged to cooperate in abutment abutment with the inertial element 2 for the protection of the longitudinal blades 3 at least against the axial shocks in the first direction Z, and the second plane of symmetry is substantially equidistant from the first axial stop 7 and the second axial stop 8.
