Abstract (en)
[origin: EP2474871A1] The index pin (1) has pin shoulders (2, 3) provided to limit a radial beat of a balance spring (20) between the shoulders and polished to support the spring. A support unit is supported on an index (10) adjusting a shoulder direction (D1) parallel to a pivot axis (D) of index in a mounting position of the pin. A sight hole (4) is in a direction parallel to the direction of shoulders, and is clear to allow visualization of the shoulders by an operator/optical instrument. A portion of the spring is inserted between the shoulders at a distance from and/or in contact with one and/or other pins.
