It also makes it possible to dispense with a friction element making it possible to maintain the mobile fixing support in a given angular position. Such a solution is therefore not subject to variations in the angular positions of a mobile fixing support, in particular after an impact.
  • Such a solution also makes it possible to minimize the size, in particular the size along the axis A1, of a balance-spring oscillator, and moreover makes it possible to integrate a hair-spring equipped with decorative motifs capable of coexisting harmoniously and consistent with other decorative motifs of the movement.
