The Tank is a typical Cartier icon, with an beautiful iteration here fitted with a flying tourbillon. The Tank Americaine Tourbillon Volant (another name for flying tourbillon) goes back the original (well the most popular at least historically) squared luxury watches.
 The difference being the intensity of the lugs as they connect to the sides of the case sandwiching the dial.
Take a look at the beautifully large crown with equally impressive sapphire crystal cabochon. Operating it lets you feel the smooth, manually wound mechanical Cartier caliber 9452MC with flying tourbillon complication and Geneva Seal. Power reserve is 50 hours.
Going along with the the style of today, the Tank Americaine is aptly large at 52mm tall and 36mm wide. The case is 18k rose gold, and the hands, as always, are heat-blued and lovely. A bold follow up to a Cartier classic.
