Abstract

A method for adjusting an oscillation frequency of a sprung balance assembly, in which a removal or a displacement of material is conducted on a component of this sprung balance assembly under an effect of a pulse of a laser source to conduct a micromachining or microfusion operation on the material of this component to vaporize or displace this material. This pulse is controlled by a controller configured to generate, sequence, interrupt any pulse and to control movements of a beam of this laser source, and the controller is automatically controlled by a measuring or comparing mechanism.
