摘要： A balance spring (1) of a sprung balance assembly of a mechanical horological movement, formed by a succession of coils (S1, . . . , Sn) which extend between a first free end, referred to as inner first coil (2), and a second free end, referred to as outer last coil (6). The are arranged off-centre when the balance spring is in the free state, the outer last coil (6) terminating in a stop means for the attachment thereof to a stud (14). The balance spring (1) is centred and its spires concentric when the spring (1) is in the mounted state inside the sprung balance assembly, the coils being rearranged concentrically when the spring is in the mounted state. The attachment of the spring to the stud inducing, in the coils, a resilient stress as a result whereof the stop is attached in a captive manner to the stud (14).
