摘要: The invention relates to a mainspring (1) including a metal strip (3). According to the invention, the metal is austenitic steel (5) in order to limit sensitivity to magnetic fields and at least the outer surface of the strip (3) is hardened compared to the rest of the strip to a predetermined depth (7) in order to harden the strip (3) in the main areas of stress while maintaining a low modulus of elasticity.
