Abstract (en)
[origin: EP1983388A1] The escapement has an escape wheel set (1) driven by a gear train, and a balance (2) associated with a balance spring. A balance launching unit uses the energy developed by the wheel set for launching the balance periodically. A wheel set locking unit locks the wheel set temporarily after each launch of the balance. Impulse pallet stones (3, 4) are secured to the balance and cooperate directly with teeth of the wheel set. A brake lever (5) is driven periodically by the balance, where the brake lever is provided with locking pallet stones (6, 7) cooperating with the teeth of the wheel set.
