Abstract
A timepiece regulating member including a balance wheel oscillating about an axis subjected to a torque exerted by a torsion return mechanism. The balance includes an attachment mechanism causing it to oscillate integrally with a torsion wire forming the torsion return mechanism specific to the balance, a largest dimension of the cross-section of a useful part of the torsion wire which is subjected to torsion is less than 100 micrometers, a smallest dimension of the cross-section of the useful part is less than 50 micrometers, a total length of the torsion wire is less than 6 millimeters, and the regulating member includes a mechanism tensioning the torsion wire.
