Abstract
A mechanical horological movement includes at least one energy storage to drive a gear train of which an output mobile component pivots about a drive axis and including a rotary resonator which has at least one central mobile component to pivot about a central axis and including an input mobile component to collaborate with the output mobile component, this rotary resonator includes a plurality of inertial elements that each pivot with respect to the central mobile component about a secondary axis perpendicular to the central axis and each returned towards a rest position, relative with respect to the central mobile component, by at least one elastic return element, and each secondary axis passes through the centre of mass of the inertial element associated with it.
