Cartier’s archives are a treasure of elegance, ingenuity, and bold experimentation, and one of the model that better exemplifies this is the Tank Jumbo automatic. While most Tanks are revered for their slim, hand-wound discretion, in the mid-1970s Cartier dared to scale up both size and technical ambition. Crafted in white gold, this rare Jumbo measures 28mm by 35mm and is immediately distinguished by its rounded case back — a subtle yet telling sign of the automatic caliber housed within. This unique feature breaks with the Tank's typically flat silhouette, marking it as the only automatic Louis-style Tank ever produced with this shape. Its iconic white dial, with printed Roman numerals and chemin de fer minute track, remains utterly timeless. The sword hands in blued steel and sapphire cabochon crown complete an ensemble that is both refined and rare. Offered with Cartier service paperwork, this example not only celebrates a pivotal moment in the maison’s mechanical journey, it wears as a quiet statement of connoisseurship and taste.
