METHOD OF SETTING THE OSCILLATION FREQUENCY OF A CLOCKWORK SUBASSEMBLY

摘要

The method involves measuring a restoring torque of component i.e. balance spring, and inertia of another component i.e. balance. The inertia of the latter component and the restoring torque of the former component are corrected, where the torque is corrected by removing material and/or addition of material and/or displacement of material and/or local/complete thermal treatment. The removal of material is performed by ablation by using an energy source remote from a surface of the latter component. The addition of material is performed by remote projection of surface of latter component.
