Our remarks

CARTIER Tank Américaine Jumbo, Ref. 1734, 950 Platinum, Silver Guilloché Dial with Roman Numerals, Manual Winding, Folding Clasp, circa 2000, Cartier Service 2025, Excellent Condition

The Tank Américaine came out in 1989. Cartier took the slim, curved case of the old Tank Cintrée and made it a little wider and more robust, and the name comes from the American market it was first developed for. This is the large model, often called the “Jumbo” by collectors, and it’s in platinum, which you see far less often than the gold versions.

The 950 platinum case measures about 26.5 by 45 mm. It’s curved lengthwise, so it follows the wrist and sits very comfortably despite its length. Platinum gives the watch a cool, quiet sheen and a pleasant weight. The crown carries a sapphire cabochon, the classic Cartier detail.

The silver dial has a fine guilloché pattern, painted black Roman numerals and blued steel sword hands. It’s the Cartier formula at its best, clear, calm and instantly recognisable. Look closely and you’ll find the hidden Cartier signature worked into one of the Roman numerals.

Inside is the manually wound calibre 430 MC, a slim, finely made movement that fits the flat, curved case well.

The watch dates from around 2000 and is in excellent condition. Cartier serviced it in its own workshop in 2025 - two years of warranty. It comes on a black aligator leather strap with a Cartier pt folding clasp.

"A Tank Américaine icon in platinum, for anyone looking for one of the great Cartier shapes in its most refined version.!"
