A skeletonised version of the 9452 MC, derived from a Roger Dubuis calibre (which came about after Cartier’s parent company acquired Roger Dubuis in 2008).

Originally conceived as a movement bearing the Poincon de Geneve, or Geneva Seal, the calibre in its latest form no longer has the hallmark, which helps make it more affordable than the Pasha de Cartier Skeleton Flying Tourbillion of 2011, which costs almost twice as much as this. That said, the movement remains largely identical in style and mechanics, including retaining the distinctive C-shaped tourbillon cage.
