Abstract (en)
[origin: EP2466401A1] The resonator has an escape wheel (6) engaged with a finishing gear so as to enable the escape wheel to be driven by an energy source of a timepiece. The wheel has permanent magnets (61-66) arranged in a manner, such that vibrations of one of arms (2, 3) of a diapason-type oscillator (1) control rotational speed of the wheel, and are periodically propagated by magnetic interaction between permanent magnets (4, 5) of the oscillator and the permanent magnets of the wheel in order to define free escapement.
