Abstract
The resonator for a timepiece includes a support structure permitting mounting the resonator in a timepiece, a first and a second balance arranged to oscillate in the same plane, at least one first and second elastic element respectively connecting the first and second balances to the support structure, the configuration of the elastic elements determining two parallel elastic pivoting axes for the two balances, and the elastic elements forming a resilient element angularly returning each of the balances towards an inoperative position. The resonator further includes a strap coupling the first and the second balance. The points joining the strap to the first and the second balance respectively are located in the same plane parallel to the plane of oscillation of the balances. When the balances are in their inoperative position, these joining points are symmetrical with respect to a center of symmetry midway between the geometrical pivoting axes.
