Abstract (en)
[origin: EP2690506A1] The balance spring (2) has a strip wound into coils (3), where an inner coil (4) is fixed to a collet (6) coaxial to the balance spring relative to a pivot axis, and an outer coil (5) is fixed to a hooking element (7). One of the coils of the balance spring includes a finger (8) mounted integrally with the coil. The finger includes a feeler spindle stud that develops in a parallel direction to the pivot axis perpendicularly to a plane in which different coils extend, where the hooking element is fixed to a flange. Independent claims are also included for the following: (1) an anti-trip mechanism for a timepiece regulating element (2) a timepiece movement (3) a method for fabricating an anti-trip mechanism.
