French jeweler and watchmaker Cartier have crafted the newest Astrotourbillon Carbon Crystal. First debuted in 2009, this latest version features Cartier’s Caliber 9460 MC movement and an off-center wheel bridge which marks the seconds. With carbon crystal components and a skeletonized center dial, this timepiece is constructed from a niobium-titanium case. The production of this mechanically advanced watch will be limited to just fifty pieces.
