Meet Cartier Tank (ref. W5310003), a contemporary classic shaped by careful watchmaking know-how. The exterior is thoughtfully executed: crafted in pink gold and measuring 29.8 mm in diameter, with a thickness of 9.5 mm, defined by a rectangular silhouette. The caseback is closed, and the crystal is sapphire, delivering water resistance to 3000 meters. At a glance, the dial balances texture and clarity: a silver tone with guilloche finish, framed by roman numerals hour markers, and sword hands. At its heart beats a proven engine: the 049 caliber. Introduced in 2012. With considered ergonomics, it feels composed during extended wear. Brushed and polished elements play with light to emphasize crisp geometry. For buyers researching specifications and real-world impressions, this reference stands out for coherent design, dependable mechanics, and lasting relevance within modern horology.
