Claim Text:
1. A forced oscillation timepiece resonator mechanism arranged to oscillate at a natural frequency and comprising, on the one hand, at least one oscillating member, and on the other hand, means for maintaining oscillations arranged to exert an impact and/or a force and/or a torque on said oscillating member, wherein said oscillating member carries at least one oscillating regulator device whose natural frequency is a regulation frequency that is comprised between 0.9 times and 1.1 times a value of an integer multiple of the natural frequency of said resonator mechanism, said integer being greater than or equal to 2 and less than or equal to 10, wherein said regulator device includes, loosely pivotally mounted on said oscillating member, at least one secondary sprung balance with an eccentric unbalance relative to a secondary pivot axis about which said secondary sprung balance pivots.
