An elegant study in proportion and restraint, this Cartier Tank Allongee from circa 1940 represents one of the most refined and elusive expressions of the Tank family. Defined by its elongated rectangular case, the Allongee stretches the original Tank concept into a slimmer, more architectural silhouetteone that feels unmistakably Parisian and quietly avant-garde for its time. Housed in yellow gold, the case remains in beautiful original condition, retaining crisp hallmarks and sharp definition throughout. Particularly notable are the so-called eagle beak lugsan early Cartier design detail characterized by their subtly pointed, sculptural profile. These lugs, often softened or lost through polishing, remain exceptionally well preserved here, lending the watch both visual tension and historical integrity. The original dial further elevates this example. Featuring Cartiers signature Roman numerals, chemin-de-fer minute track, and blued steel hands, it exhibits gentle, honest aging consistent with a watch that has been carefully worn rather than restored. The proportions of the elongated case frame the dial beautifully, emphasizing verticality and lending the watch an elegance that feels both formal and effortlessly wearable. Measuring 21.5mm in width by 39mm in length, the Tank Allongee wears with surprising presence despite its slender profileequally at home under a cuff or worn as a statement of quiet connoisseurship. Produced in far smaller numbers than standard Tank Normale or Louis Cartier models, the Allongee remains a deeply collectible reference, prized by seasoned Cartier collectors for its rarity, design purity, and unmistakable 1940s character. This example features a LeCoultre movement, correct for the period. This is Cartier at its most intellectual: refined, architectural, and timelessan enduring expression of form over ornament, preserved in remarkable original condition.
