Cartier 9459 MC

The 9459 MC is a manual-winding in-house caliber from Cartier, introduced in 2014 as part of the manufacturer's MC (Manufacture Cartier) family. It powers the Rotonde Astrocalendaire tourbillon, featuring a complex astronomical complication that displays perpetual calendar functions alongside the flying tourbillon. The movement is produced in limited quantities, reflecting its high-complication status within Cartier's contemporary catalog.
