The Cartier Tank Allongée Ref. 1380 is an elegant Art Deco expression in yellow gold that elongates the classic Tank form with graceful proportions. Measuring 14.4 mm wide by 35.5 mm long, this slim rectangular case is fitted with a three-row diamond bezel across the top and bottom, adding refined sparkle without overpowering its design. The ivory dial features slender Roman numerals at the XII and VI, blued-steel sword hands, and Cartier’s signature cabochon crown—creating timeless balance and heritage elegance in a compact silhouette.

Powered by a precise quartz movement, this Allongée model is made for dress-watch elegance and ease of wear. Released in the vintage Cartier line, its yellow gold case, fine diamond setting, and elegant proportions make it rare in well-preserved condition. For collectors who appreciate boutique craftsmanship and subtle but unmistakable luxury, the 1380 Allongée offers decorative refinement wrapped in Cartier’s architectural legacy—quietly spectacular on the wrist.
