Abstract
An inertial mass (1) intended to be mounted on a regulating organ (10), particularly of a horological movement, the inertial mass being configured to be subjected to a rotary oscillation movement at a predetermined frequency, the inertial mass including a rigid main body (2), characterised in that it comprises a flexible inertial element (3) assembled with the main body (2), the flexible inertial element (3) being configured to modify the geometry of the inertial mass (1) according to the oscillation amplitude. Also, a regulating organ and a horological movement comprising such an inertial mass.
