Cartier Must de Tank Vermeil ‘Onyx’ Big Size Manual Wind circa 1980’s

This Cartier Must de Tank Vermeil is a beautifully balanced expression of Cartier’s late-20th-century design language, presented here in its most minimalist and striking form: the ‘Onyx’ coloured dial. The vibrant black lacquered surface gives the watch a playful yet unmistakably Parisian character, while the absence of numerals places full emphasis on the purity of the Tank’s geometric design. It’s a dial variation that has become one of the most beloved and distinctive within the Must de Cartier collection.

The vermeil case — sterling silver coated with gold plating — has the warm presence of yellow gold combined with the weight and feel of solid silver. As the largest model in the Must de Cartier Tank line-up (23 x 30 mm), this example offers a more substantial wrist presence while maintaining the elegance and proportions that define the Tank.

Inside, the manual-wind Cartier calibre 78-1 provides a traditional, tactile watchmaking experience. The movement was serviced in November 2025 and comes with a one-year warranty, ensuring dependable performance.
