To mark the Tank’s 100th birthday, Cartier released three new models of this iconic timepiece, which has been favoured by the likes of Mohammad Ali, Yves Saint Laurent, Warren Beatty and Ingrid Bergman. However, it was the purest and most classic of them all that has won the hearts of Cartier fans around the world. If you needed just one classic timepiece, it would be the Cartier Tank Louis Cartier. Available in a small or large, it is encased in 18K pink gold, embellished with a blue sapphire cabochon set in the fluted. The guilloche on the dial lends a lovely backdrop to the signature Roman numeral dial with a silvered finish. It features a semi-matt brown alligator strap with ardillon buckle.
