ABSTRACT:
The escapement includes a large plate4carrying a first finger14and a blocking member6carrying a second finger11and a locking pallet-stone7. The first and second fingers14and11are shaped such that when the large plate4rotates in a first direction a, the first finger14drives the second11which moves around a first side20of said first finger to release the locking pallet-stone. Re-engagement occurs when the second finger11climbs over a vertical flank25of a notch22made in a small plate23. When the large plate4rotates in a second direction b, opposite to the first, the first finger14drives the second finger11which moves around a second side21, opposite to the first, of said first finger14to keep the locking pallet-stone7in the escapement wheel.
