Abstract (en)
[origin: EP2728423A1] The assembly (1) has a balance wheel (2) pivoting around a pivoting axis (D) and a hair spring (3) comprising an inner turn (4) fixed to the wheel or to a ring (5) mounted to the spring. An outer turn (6) is fixed at a stud (7) to maintain the turn at a plate or balance coq. The wheel has a peripheral surface (20) at a distance from any point of the spring at value greater than variation (E1) to prevent modification of characteristics of the hairspring during resumption of machining of the hairspring on the surface for setting inertia or/and balancing of the wheel on the assembly. Independent claims are also included for the following: (1) an oscillator mechanism (2) a method for setting inertia or/and balancing a balance wheel on clockwork balance wheel-hairspring assembly.
