Rotonde de Cartier single push-piece tourbillon chronograph watch
Manual, pink gold
In 2005 and for the first time in watchmaking history, Cartier presented a movement that combined two key complications - the single push-piece chronograph and the tourbillon - in the caliber 9431 MC.
This highly original combination gave rise to the Rotonde de Cartier tourbillon single push-piece watch, which is distinguished by both its exceptional technical characteristics and delicate silhouette. A platinum case houses this outstanding complication and displays the elegance of a contemporary, pared-down design.
Numbered edition limited to 50 timepieces. Tourbillon complication combined with a single push-piece chronograph.
