Visual Description
The original Tank Cintrée presents one of the most striking silhouettes in all of horology. At 23 × 44.7 mm, the case is dramatically elongated — far taller and narrower than any Tank before or since in standard production. The defining characteristic is the curved case profile: viewed from the side, the case arcs gently from lug to lug, creating a watch that conforms to the shape of the wrist rather than sitting flat atop it. The white dial carries Roman numerals that have been subtly stretched to accommodate the elongated dial aperture — a design detail unique to the Cintrée that gives the dial a visual tension absent from other Tanks.
Reference Significance
This is where the Tank Cintrée began. The earliest examples from the 1920s and 1930s represent some of the most historically significant and valuable wristwatches in existence. They were produced entirely by hand in Cartier's ateliers, each case individually crafted and finished. The round 18-jewel movement, designed by Edmond Jaeger and signed EWC (European Watch and Clock Company), reflects the close collaboration between Cartier and the Jaeger workshop that defined early twentieth-century Parisian watchmaking.
Production numbers for early Cintrées are unknown but were undoubtedly very small — this was Cartier's most exclusive wristwatch design, offered only in precious metals and priced accordingly. Surviving examples from the interwar period are museum-grade pieces. When they appear at auction, they command prices that reflect not just their rarity but their importance to the history of wristwatch design.
Historical Context
The early 1920s were the formative years of the wristwatch as a category. The Tank Normale had established the rectangular case as a viable alternative to the round pocket watch form, but the design space was wide open — no consensus existed about what proportions, shapes, or case constructions would prove enduring. The Cintrée was Cartier's most adventurous exploration of that open design space: a dramatically elongated rectangle with a curved case back, combining Art Deco geometry with ergonomic innovation.
That this design has remained in continuous production for over a century — while countless other experimental case shapes from the same era have been forgotten — speaks to the rightness of the original vision. The Cintrée's proportions have not been substantially altered since 1921. The curved case back, the elongated brancards, the stretched numerals: these elements were correct from the beginning.
What to Look For
Early Cintrées require expert evaluation. Key points include: hallmarks consistent with the claimed production period and Cartier house (Paris, London, or New York — each had distinct markings), movement signed EWC or with appropriate period-correct caliber identification, case metal consistency (gold, platinum, or in rare instances silver), and overall proportions matching known examples. The curved case back should show a smooth, continuous arc without flat spots or dents. Given the age and rarity of interwar examples, provenance documentation — prior auction records, dealer history, collection pedigree — is exceptionally important.
