Cartier

The present Cartier Tank Rectangulaire from circa 1960 is a beautifully preserved example of Cartier’s mid-century design language, distinguished not only by its elegant proportions but also by the presence of the renowned Piaget 9P movement. A collaboration between two of the era’s most respected maisons, the pairing of Cartier’s iconic case design with Piaget’s ultra-thin mechanical expertise results in a watch of exceptional refinement.

Introduced in 1957, Piaget’s 9P quickly became one of the world’s thinnest hand-wound calibers and was celebrated for its reliability, finishing, and remarkable slimness. Its integration into Cartier’s Tank models allowed for a sleeker, more sophisticated profile, enhancing the watch’s already timeless silhouette. The slender case, elongated rectangular form, and classic Roman numeral dial bring forward the purity and restraint that have defined the Tank for over a century.

Surviving examples from this period—particularly those housing the coveted 9P—are increasingly scarce, as many were produced in very limited numbers. This 1960 Tank Rectangulaire represents a rare opportunity to acquire a historically significant collaboration between Cartier and Piaget, embodying the pinnacle of mid-century elegance and mechanical artistry.
