Abstract (en)
The sub-assembly (1) has a bridge (3), and a balance spring (71) whose outer end is secured to a balance spring stud (73). The balance spring and the spring stud are connected to form a single-piece assembly with the bridge. The spring stud is designed in a position-adjustable manner and locked in a pre-adjusted position by a locking unit. The spring stud is fixed to the bridge by an elastic return unit, where the balance spring comprises an outer coil (77) that is clamped by two pins. One of the pins is secured to the bridge by the return unit.
