Rotonde de Cartier tourbillon chronographe monopoussoir

For the first time in the history of watchmaking, the calibre 9431 MC movement has combined two of the most outstanding complications: the single push-piece chronograph and the tourbillon. This movement was developed exclusively for Cartier in 2005 by one of the most celebrated names in Swiss fine watchmaking: Renaud & Papi. The transparent sapphire crystal case-back enables the calibre to be observed along with its major components, such as the tourbillon or the operating lever, which is linked directly to the to both the winding mechanism and the column wheel and controls the functions: start, stop and reset. It also enables both sides of the tourbillon to be observed. This movement also benefits from the exceptional finishes that are characteristic of the movements in the Cartier Fine Watchmaking Collection.

A precious case

The graphical, platinum case of the Rotonde de Cartier single push-piece chronograph displays modern minimalist elegance. The aesthetics of this case are inspired by the contrasting design of a two-level dial, the first guilloché, the second skeletonised. Characteristic Cartier style, echoed by the C-shaped bridge.
