Abstract
The watch movement includes a mechanical resonator with a balance and a spring, a device for setting the oscillation frequency of the mechanical resonator and a device for setting the guide mark on the mechanical resonator. A moving part of the setting device includes a fastener for attaching an outer end part of the spring and a device for defining the active length of the spring. A mechanism for varying the active length of the spring includes a first toothed wheel, carried by the moving part, and a first toothing, arranged along the outer end part of the spring, with which the first toothed wheel meshes. The fastener holds the outer end part by friction such that the first toothed wheel can drive this outer end part via the first toothing and thus vary the active length of the spring.
