Cartier Tank Must de Vermeil Black Onyx Dial GM From 1980s

An elegant and highly collectible Cartier Tank Must de Vermeil GM from the 1980s, distinguished by its striking original black lacquer “Onyx” dial. Combined with the larger GM proportions and mechanical manual-wind movement, this is a particularly attractive expression of the vintage Tank Must.

The classic 23 × 30 mm vermeil case offers a wonderful presence on the wrist while retaining the refined proportions synonymous with the Cartier Tank.

Its defining feature is the beautiful original Cartier black lacquer dial, often referred to as the “Onyx” dial. Free from traditional numerals, the deep black surface gives the watch an exceptionally clean and minimalist appearance. The lacquer shows a light natural spider effect, adding authentic vintage character to the dial.

Golden hands provide an elegant contrast against the deep black dial, while Cartier’s signature blue sapphire cabochon crown adds the unmistakable finishing touch.

Inside beats the Cartier Calibre 78-1 manual-wind mechanical movement, freshly serviced by our watchmaker and running excellent. The watch is accompanied by a one-year service warranty.

It is fitted with a handmade Belgian black leather strap and a standard gold-plated pin buckle.
