Abstract
The invention relates to a rotating oscillator for a timepiece comprising a support element designed to allow the oscillator to be assembled on a timepiece, a balance, a plurality of flexible blades connecting the support element to the balance and able to exert a return torque on the balance, and a felloe mounted secured to the balance. The plurality of flexible blades comprises at least two flexible blades, including a first blade positioned in a first plane perpendicular to the plane of the oscillator, and a second blade positioned in a second plane perpendicular to the plane of the oscillator and intersecting the first plane. The geometric oscillation axis of the oscillator is defined by the intersection of the first plane and the second plane, said geometric oscillation axis crossing the first and second blades at ⅞th of their respective lengths.
