Cartier Tank Louis Cartier W5310012

Cartier Tank Louis Cartier Skeleton Sapphire reference W5310012 is a luxury men's timepiece characterized by its intricate open-worked design that creates the illusion of a floating movement. Housed in a polished 18kt white gold rectangular case measuring 30mm x 39.2mm, it features a unique patent-pending transparent sapphire crystal mainplate that supports the mechanical components. The watch is powered by the Manufacture Calibre 9616 MC manual-winding movement, which consists of 159 parts and 21 jewels, offering a power reserve of approximately 72 hours. Complementing its avant-garde architecture are traditional Cartier hallmarks, including blued steel sword-shaped hands, a beaded crown set with a sapphire cabochon, and a black leather strap with a white gold folding buckle. The piece is water-resistant to 30 meters (3 bar) and is finished with sapphire crystals on both the front and the exhibition case back, allowing for total transparency.
