ABSTRACT:
The escapement includes first (1) and second (2) escape wheels each driven by independent gear trains and barrels. The system includes a brake lever (8) cooperating with an impulse pin (7) of the roller (4) and with the escape wheels via locking pallet stones (12, 13). The roller carries pallet stones (10, 11) for receiving impulses from the escape wheels. When the wheels are locked, the brake lever occupies a centred position relative to said wheels. Means (16, 30, 31) for re-engaging the locking pallet stones in the toothing of the wheels are provided to ensure proper operation of the system.
