Abstract
A spiral spring for a horological resonator mechanism, including a flexible strip () coiled on itself into several turns The spring () including an element for adjusting its stiffness, which includes a first elongate flexible element (), and a second elongate flexible element () arranged in series with the strip (), each elongate flexible element () connecting the same end () of the strip () to a fixed support (), so as to add an additional stiffness to the strip (), each elongate flexible element () preferably having a stiffness higher than that of the strip (). A prestressing element () applies at least two different adjustable efforts, the two efforts being applied on the first elongate flexible element () so as to make the stiffness of the first elongate flexible element () vary according to the prestress level.
