摘要： In an oscillator for a timepiece including a balance and a hairspring, the balance lacks equilibrium, such that: the curves for running of the oscillator owing to weight of the hairspring as a function of the oscillation amplitude of the balance in at least four vertical positions of the oscillator spaced by 90° each pass through 0 at an oscillation amplitude of the balance between 200° and 240°; and between oscillation amplitudes of 150° and 280°, curves representing the running of the oscillator owing to lack of equilibrium in the balance as a function of the oscillation amplitude in the vertical positions each has an average slope of opposite sign to the average slope of the corresponding curve among the curves representing the running of the oscillator owing to the weight of the hairspring. A reduction in the running discrepancies between the vertical positions can thus be achieved.

摘要： 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.
