Abstract (en)

[origin: EP2063325A2] The movement has a regulating unit provided with a balance (1) and concentric hairsprings (3, 5), where exterior ends (30, 50) of the hairsprings are integrated to the balance. Interior ends of the hairsprings are integrated to a fixed staff (7) of the balance, where the hairsprings are made of silicon or light metal alloy. The balance pivots around the staff integrated to a plate of the movement. Guiding elements are integrated to the balance for ensuring lateral and axial guiding of the balance on the staff.
