Cartier 'Must De Cartier' Tri-Tone Tank

There are iconic watches, and then there are watches that have transcended watchmaking altogether. The Cartier Tank belongs firmly in the latter category. Since its introduction in 1917, its clean geometry and architectural lines have remained remarkably unchanged, proving that truly great design rarely requires reinvention. Artists, royalty, tastemakers, and collectors have all worn the Tank, yet somehow it continues to feel as modern today as it did more than a century ago. This particular example comes from the celebrated Must de Cartier collection, introduced in the late 1970s as a more accessible expression of Cartier's most famous designs. While many Must models embraced bold monochromatic dials, this reference takes a different approach, showcasing one of the most distinctive dial executions of the era. Housed in a 24mm x 31mm gold-plated case, the watch features a captivating tri-frame metallic dial whose layered geometric design transforms the familiar Tank into something altogether more playful and expressive. The stepped framing effect creates depth and dimension, while retaining the clean elegance that has always defined the model. Cartier's signature blued-steel hands sweep across the dial beneath the original double Cartier signature, complete with the intertwined "CC" monogram—a charming reminder of the period in which it was produced. The classic sapphire cabochon crown remains present, of course, while inside beats a manually wound movement that reinforces the mechanical appeal collectors increasingly seek in vintage Must models. Paired with a black leather strap and period-correct gold-tone pin buckle, this Tank occupies a sweet spot in the Cartier universe: instantly recognizable, undeniably stylish, and just unusual enough to stand apart from the crowd. The Must de Cartier line was never intended to be ordinary. Pieces like this remind us just how creative Cartier was willing to be when given the freedom to experiment. Because even an icon like the Tank occasionally benefits from a little disco-era swagger.
