Abstract
A watch including a movement including itself an isochronous timepiece oscillator mechanism including a fixed support bearing a crosspiece carrying N primary resonators each including a weight carried by a rotating flexible bearing fixed to this crosspiece. Each primary resonator has a center of mass which, at rest, is on the virtual pivot axis of its rotating flexible bearing and is arranged to oscillate in rotation about this virtual pivot axis. The primary resonators are arranged in rotational symmetry of order N about a main axis parallel to the virtual pivot axes, and oscillating motions of any two primary resonators are phase shifted by the value of the central angle formed by their respective virtual pivot axes with the main axis.
