PROBLEM TO BE SOLVED: To provide an oscillator comprising a resonator of the inertia-elasticity type, cooperating with a detent escapement, which is reliable, compact and not subject to tripping and whose machines are very precisely positioned in relation to each other.SOLUTION: The invention relates to an oscillator 101 including a resonator 105 of the inertia-elasticity type cooperating with a detent escapement including a detent 107 cooperating with an escape wheel 109. The resonator 105 is in one piece and includes an inertia member and a first flexible structure providing the elasticity and forming a virtual pivot axis of the resonator 105, and the detent 107 is in one piece and includes an unlocking spring and a second flexible structure forming a virtual pivot axis of the detent 107.SELECTED DRAWING: Figure 7 |
