One of the most intriguing watches created by Cartier thus far is the new Ballon Bleu Tourbillon. The Ballon Bleu Tourbillon is Cartier's first that incorporates the brand's new 9452MC tourbillon movement, which bears the Geneva Seal hallmark. The 9452MC movement is mechanical with manual winding, it is comprised of 142 hand-finished parts and 19 jewels and has a power reserve is 50 hours.

The Cartier Ballon Bleu gets its name from the sapphire cabochon crown which is incorporated into its rounded case and this version is no exception. It is crafted from 18K pink gold, and it measures 46mm across which makes it larger than even the Grand Modele Ballon Bleu which is only 42mm in diameter. The watch also features sapphire crystal on the face as well as the transparent case-back of the watch. The dial has a three-dimensional guilloche silvered look with sun-ray open-worked grid. The watch has Roman numeral markers and sword-shaped, blued-steel hands. The tourbillon carriage is positioned in an untraditional way so that appears to float freely above the dial adding to the already impressive design..
