FIELD: physics.
SUBSTANCE: mainspring (1) includes a metal band (3). According to the invention, the metal is austenitic steel in order to limit the sensitivity to magnetic fields, and, at least, the outer surface of the tape (3) is strengthened, compared to the rest of the tape, by a predetermined depth (7) in order to strengthen the tape (3) in the main zones of mechanical stress, while maintaining a low elasticity module. The present invention relates to clock drums.
EFFECT: simplified design.
