Definitions

  • the output of the resonator 3 may be disturbed by vibrating elements 31 resonating at different frequencies.
  • the efficiency of the resonator 3 can also be disturbed by the resonance of the vibrating elements 31 which are fixed at one of their ends to the same base 2 and at the other end to the same mass element 32, and which would oscillate with different amplitudes. It is therefore advantageous for the vibrating elements 31 to resonate substantially at an amplitude (radial or transverse) which is substantially the same.
  • the two mass portions 32 ' are rigidly connected, so that the blades 31' and the mass portions 32 'oscillate substantially at the same frequency and the same amplitude.
  • the oscillator 1 comprises an on / off mechanism 60 comprising a lever 61 actuated by the pull tab 62 of a time-setting mechanism and configured to stop and maintain stopping the oscillator 1, stopping the vibrating elements 31 of the oscillator 1 in an unbalanced position, corresponding to one of the two extreme positions of the resonator 3 in normal operating mode (or an eccentric position relative to the escape wheel 5) so as to provide a self-starting function of a watch movement.
  • the oscillator 1 is turned on in the first oscillation mode.
  • the resonator 3 may be made of silicon and the thermocompensation obtained by providing a material having a thermoelastic coefficient of opposite sign to that of silicon, and distributed uniformly or discontinuously on the surface and / or within the material composing the vibrating elements 31.
  • the thermocompensation material may be a silicon dioxide (Si0 2 ).
