Abstract
A resonator of the inertia/elasticity type includes a balance-spring coupled to an inertia flywheel and a system for adjusting the frequency of the resonator including an index-assembly arranged to cooperate with one coil of the balance-spring in order to selectively choose the active length of the balance-spring. The portion of the coil of the balance-spring cooperating with the index-assembly includes at least one area of larger cross-section than the other balance-spring coils for finer adjustment of the frequency of the resonator.
