Abstract (en)
[origin: EP2781970A1] The mechanism has pins (74, 74A, 74B) for clamping or touching an outer coil (77) of a timepiece balance spring (71) during operation of the balance spring, where the pins are in a single piece with a bar. The pins are secured to the bar by an elastic return unit (76) that is in a single piece with one of the pins and the bar, and tend to move one pin closer to the other pin. The balance spring is in a single piece with a balance spring stud and the bar. The integrated elastic return unit is pre-stressed in a silicon oxide state, where the mechanism is made of silicon.
