Abstract

See full text

A timepiece movement, including a mechanism including an inertial element arranged to oscillate or pivot about a first axis of pivoting relative to a structure of the movement, and arranged to cooperate directly or indirectly with an energy distribution wheel set that pivots relative to the structure about a second axis of pivoting parallel to or coincident with the first axis of pivoting and subjected to a torque exerted by an energy source, wherein the energy distribution wheel set meshes directly or indirectly with at least one inertia wheel set that pivots about a third axis of pivoting relative to the structure, each inertia wheel set is arranged to pivot in the opposite direction to the energy distribution wheel set, and the total inertia of the inertia wheel sets is between 60% and 140% of the inertia of the energy distribution wheel set.
