    摘要： Watch with a timepiece movement, a resonator mechanism, including a magnetic escapement mechanism including an escape wheel set including a magnetized track, with a succession of areas according to a scrolling period in which its magnetic features are repeated, each area including an increasing magnetic field ramp followed by a magnetic field barrier with an increasing field and of higher field gradient that that of the ramp, the track includes a continuous, closed magnetic layer over the entire periphery of the escape wheel set, of constant thickness and variable width, whose geometry defines these magnetic field ramps and barriers, this escape wheel set cooperating with a sprung balance via a pivoting magnetic stop member comprising a pole piece arranged to cooperate alternately with an internal track and an external track of the magnetic layer.

    摘要： A method for maintaining and regulating frequency of a timepiece resonator mechanism around its natural frequency, the method including: at least one regulator device acting on the resonator mechanism with a periodic motion, to impose a periodic modulation of resonant frequency or quality factor or a position of a point of rest of the resonator mechanism, with a regulation frequency between 0.9 times and 1.1 times the value of an integer multiple of the natural frequency, the integer being greater than or equal to 2 and less than or equal to 10, and the periodic motion imposes a periodic modulation of the quality factor of the resonator mechanism, by acting on losses and/or damping and/or friction of the resonator mechanism.
