Timepiece oscillator mechanism

A timepiece oscillator comprising a structure and/or a frame, and a plurality of distinct, temporally and geometrically offset, primary resonators, each comprising at least one inertial mass returned to said structure or to said frame by an elastic return means, wherein said timepiece oscillator includes coupling means arranged to allow the interaction of said primary resonators, said coupling means including a wheel set subjected to a torque or a drive force, said wheel set includes drive and guide means arranged to drive and guide a control means, which is articulated with a plurality of transmission means, each articulated, remote from said control means, with a said inertial mass of a said primary resonator, and further wherein said primary resonators and said wheel set are arranged such that the axes of articulation of any two of said primary resonators and the axis of articulation of said control means are never coplanar, wherein said primary resonators are rotating resonators, and wherein the centres of mass of said primary resonators remain, during the normal oscillations of said primary resonators, in immediate proximity to the centres of rotation of said primary resonators.
