Measuring 41 mm × 31 mm, the stainless steel case of the Tank Must Extra Large stays true to the Tank's enduring rectangular form. The crown is beaded and set with a synthetic cabochon-shaped spinel, a refined detail that nods to Cartier's long history of gem-set design. Water resistance reaches 3 bar (approximately 30 meters / 100 feet).
Beneath the scratch-resistant sapphire crystal, a silvered flinqué dial pairs Roman numeral hour markers with blued-steel sword-shaped hands, offering a clean and legible face that carries unmistakable Cartier character. The movement within is the Caliber 1847 MC automatic, delivering hour, minute, second, and date functions with Swiss-made precision.
The watch sits on a stainless steel bracelet secured by a fold clasp and is presented complete with its original box and papers — making it a compelling choice for both the dedicated collector and the first-time Cartier enthusiast.
