Cartier Cpcp Tank Basculante 2391 Millenium Watch
Cartier CPCP Tank Basculante 2391 Millennium: A Rare Horological Treasure
The Cartier CPCP Tank Basculante 2391 Millennium Watch is an extraordinary relic from the prestigious Collection Privée Cartier Paris (CPCP), representing the golden era of Cartier’s mechanical watchmaking. Released in 1999 to commemorate the turn of the millennium, this limited-edition timepiece is one of only 365 pieces ever produced. It features a stunning 18K yellow gold case with a unique “cabriolet” system that allows the watch face to flip vertically within its frame. The dial is a masterclass in classical design, showcasing a central rosette guilloché pattern, traditional Roman numerals, and the “Cartier Paris” signature that denotes its elite CPCP lineage.
Bespoke Craftsmanship and Rare Millennium Symbolism
What sets the Reference 2391 apart is its profound attention to historical detail and symbolic engraving. The reversible case back is beautifully engraved with the years “1999/2000/2001”, marking the bridge between centuries. Beneath the silvered dial lies the ultra-thin, manually wound Calibre 060 MC (based on the Frédéric Piguet 6.10), a movement prized by collectors for its slim profile and technical reliability. When tilted mid-rotation, the Basculante can stand upright on a flat surface, transforming from a sophisticated wristwatch into a miniature desk clock. This is not just a watch; it is a highly sought-after investment piece that embodies the soul of Cartier’s heritage.
