Summary:Timepiece regulator comprising a detached lever escapement mechanism, and a resonator with a quality factor Q including an inertia element including an impulse pin cooperating with a fork of the lever, subjected to the return force of two flexible strips attached to the plate, defining a virtual pivot having a main axis (DP), the lever pivoting about a secondary axis (DS), and the lift angle (β) of the resonator, during which the impulse pin is in contact with the fork, is less than 10°, and the ratio IB/IA between the inertia IB of the inertia element with respect to the main axis (DP) and the inertia IA of the lever with respect to the secondary axis (DS) is greater than 2Q·α2/(0.1·π·β2), where α is the lift angle of the lever corresponding to the maximum angular travel of the fork.
