Abstract
An escapement for a mechanical watch comprising: an escapement wheel () kinematically connected to a power source, a roller () mounted on a balance () including, on two different levels, a pin () and an impulse pallet () co-operating with said wheel (); a limiting member () performing a periodic movement during which it co-operates with the pin () to limit the travel of said roller (); a control member () provided with a rest lift () performing, from a stable position wherein said wheel () is pressed on the rest lift (), a periodic movement during which the wheel is released and provides an impulse to the impulse pallet (). The periods of the limiting member () and of the control member () correspond, respectively, to an alternation and an oscillation of the balance.
