The invention relates to an oscillator comprising a pivoting staff connected to a mechanical energy source, an inertia-elasticity resonator formed in one piece, which is mounted on the pivoting staff, a detent escapement comprising a single-piece detent fixed to the pivoting staff, which comprises at least one flexible blade and a stop member arranged to elastically lock the pivoting staff in relation to a concentric escapement toothing, wherein the release element is arranged to elastically unlock the stop member in relation to the concentric escapement toothing, by the movement of the member forming the inertia, so that the pivoting staff counts each oscillation of the resonator while transmitting to it the energy able to maintain it.

A pendulum includes a movable body connected to a stationary supporting structure for oscillation in a fixed vertical plane. The pendulum further includes a control and stabilization system for controlling and stabilizing the oscillation amplitude of the movable body. The control and stabilization system includes a braking device which includes a permanent magnet and an electrically conductive element, one of which is attached to the movable body and the other of which is connected to the supporting structure such that when the movable body approaches one end of the oscillation field, the generated magnetic flux causes a braking of the movable body's motion. The quality factor Q of the pendulum is substantially proportional to the inverse of a power, at least equal to the square, of the amplitude of the oscillation of the movable body with the amplitude is close to the desired amplitude of oscillation.
