Estimating the term…
A balance-spring, in particular for a horological resonator mechanism, the balance-spring including a flexible strip coiled on itself into several coils, the strip having a predefined flexibility, the balance-spring including a device for adjusting its flexibility, the adjustment device including an elastic element in direct contact with the strip, the elastic element preferably having a flexibility less than that of the strip, the adjustment device including a prestressing device to apply a variable force or torque to the elastic element, so as to vary the flexibility of the elastic element, the elastic element and the strip being separate and assembled with each other. An horological resonator mechanism including such a balance-spring is also disclosed.
A balance-spring for a horological resonator mechanism, the balance-spring comprising a flexible strip coiled on itself into several coils, the strip having a predefined flexibility, the balance-spring including adjustment means for adjusting its flexibility, the adjustment means including an elastic element arranged in series with the strip, the elastic element connecting one end of said strip to a fixed support, so as to add an additional flexibility to the strip, the elastic element preferably having a flexibility less than that of the strip, the adjustment means including prestressing means to apply a variable force or torque to the elastic element, preferably without substantially modifying the position of the end of the strip, so as to vary only the flexibility of the elastic element, characterised in that wherein the elastic element and the strip are separate and assembled with each other by assembly means.
