Calibre de Cartier Diver

Cartier's first-ever diving watch was one of this year's most anticipated timepieces. Part of the masculine Calibre de Cartier collection, the ISO-certified dive watch features all the traditional Calibre traits: sword-shaped hands, Roman numerals arching across the 42mm dial, and a curved calendar window. Underwater, the unidirectional dial morphs delightfully: The calendar and most of the numerals disappear while glowing Super-LumiNova pigments highlight the dive-time indicators, hands, and the bezel's triangular marker. At 11mm thick, it's the thinnest diving watch on the market today and it can handle a depth of up to 300 meters, thanks largely to its oversize seals. The watch can come on either a rubber strap or metal bracelet and, because Cartier timepieces will always be as much about luxury as they are about practicality, is available in stainless steel, pink gold, or a two-tone option.
