Abstract
The invention relates to a timepiece including a resonator cooperating with an escapement system. According to the invention, the escapement system includes a moving escape wheel arranged coaxially to the balance and driven by the gear train of the timepiece, a first fixed wheel having a first toothing and a second fixed wheel having a second toothing, the first and second fixed wheels being arranged coaxially to the moving escape wheel and a device for securing the outer end of the balance spring including a part hinged relative to the moving escape wheel and arranged to ensure a radial movement of the outer end between the first and second toothings to maintain the resonator and to transmit the motion thereof to the timepiece gear train.
