CARTIER Tank Louis Cartier 25.5mm large 18-karat gold and alligator watch

Setting the standard to be upheld by all 'Tank' watches, Cartier's 'Louis' timepiece is hailed as the brand's most legendary style - it's been worn by icons like Princess Diana and was the preferred choice of Louis Cartier himself. This large version is cast from 18-karat gold and has a silvered dial and timeless brown alligator strap. The crown is topped with a sapphire cabochon - we love how the striking shade is echoed in the signature sword-shaped hands.

All Cartier watches still within the initial 2-year warranty period under the original International Limited Warranty will be eligible to benefit from a 6-year extension, for a total of 8 years warranty.
