Cartier Must De Tank Vermeil Big Model ‘Trinity Dial’ Mechanical circa 1980’s

This Cartier Must de Tank Vermeil is a beautifully preserved example of one of Cartier’s most recognizable designs, presented here in its most striking and minimal interpretation: the trinity mirror dial. With its reflective surface and absence of numerals, the dial captures light in a uniquely elegant way while highlighting the pure geometric form of the Tank. The result is a design that feels both vintage and modern — unmistakably Cartier, yet refreshingly bold.

The vermeil case, crafted in silver with a layer of gold plating, gives the watch a warm, refined presence. As the largest model of the Must de Cartier Tank line-up (23 x 30 mm), it offers a more commanding wrist presence while retaining the classic proportions that have made the Tank an enduring icon.

Inside ticks the manual-wind Cartier calibre 78-1, delivering a tactile, traditional watchmaking experience. The movement was serviced in November 2025 and comes with a one-year warranty, ensuring reliable performance. Completing the set is an original, unworn Cartier strap and the original Cartier box — highly desirable details for collectors of vintage Cartier.

Highlights

• Original unworn Cartier strap
• Original Cartier box
• Biggest model of the line-up with manual-wind movement
