Cartier Must Tank Manual 'Lapis' Dial, 1980s

Dealer description — Huntington Company

History and Significance The so-called Lapis Tank does not use real lapis stone. The Must de Cartier stone dials were lacquer-painted to resemble materials like onyx and lapis. Even so, the effect is impressive. The deep blue lacquer with gold-toned flecks gives the watch a distinctive look while still preserving the elegance of the Tank design. It is an appealing way to add color without leaving the dress watch category. The Must de Cartier line was introduced in the mid 1970s as a way to broaden Cartier’s audience while keeping the visual identity of the brand intact. These watches were made from sterling silver with thick gold plating. The line became a major milestone, marking Cartier’s first non-precious metal watch and its first mass-produced model. Production grew from roughly 3,000 watches per year to more than 160,000 by the end of the decade. The range included faux-stone dials, wood-style lacquer, tortoiseshell effects, and the well-known Trinity dial. The Lapis-style dial remains one of the most recognizable and frequently admired variants. Writer’s Thoughts This Tank feels familiar in size and layout, but the blue lacquer dial changes the mood entirely.
