1960's Jaeger Le Coultre Mini Tank Yellow Gold Ref. 6028.21

The Tank by Jaeger-LeCoultre — Mini Gold Elegance

The Cartier Tank, first introduced in 1917, revolutionized rectangular watch design with its clean lines and Art Deco appeal. But while Cartier set the template, it didn’t own the category — and Jaeger-LeCoultre, one of the most innovative maisons in horology, made its own sophisticated interpretation. This rare Mini Tank by Jaeger-LeCoultre, produced in the golden era of the 1960s, is a tribute to that legacy, fusing Parisian elegance with watchmaking excellence.

Crafted entirely in 18K gold, the case of this piece remains rich in color and weight, exuding a solidity not often found in vintage miniatures. The condition of the case is exceptional — deeply struck French owl hallmarks confirm its origin, while legible serial and reference numbers place its production squarely in the mid-century period. The presence of the sapphire cabochon crown, a nod to both Cartier tradition and JLC refinement, completes the look.

The dial has aged with charm, shifting to a soft off-white patina, and is adorned with bold Roman numerals in true Art Deco fashion. Instead of a traditional railroad minute track, the dial’s minimalist balance allows the “Jaeger-LeCoultre” signature — underlined with pride — to stand out. Blued sword hands tie everything together, delivering an aesthetic that's both delicate and strong.

Inside, a hand-wound mechanical movement keeps time reliably. It’s paired with a generic leather strap and pin buckle, though the watch is also accompanied by its original 18K gold deployant clasp — a rare and beautiful addition. While the deployant doesn't allow for strap resizing, it invites the new owner to personalize their fit with a custom strap of their choice.

With a case size of 25x19mm, this is a true Mini Tank, perfect for slender wrists or collectors who appreciate smaller proportions. For those seeking an elegant vintage Tank that deviates from the mainstream Cartier path, this Jaeger-LeCoultre represents a beautiful and rare opportunity.
