The link between the cal. 03.03-L and the movement in the Superfast Chrono (and, for that matter, the L.U.C 1963 Chronograph) is undeniable. The Chrono One and its movement were, in essence, Chopard's gift to itself, and all of us, in celebration of the 10th anniversary of the Chopard Manufacture in 2006. The 03.03-L is is a fully integrated column-wheel chronograph with a vertical clutch equipped with what Chopard has called "a friction organ in a viscoelastic material." (Someone more knowledgeable than me will have to help with that one.)
