Just because it’s called a “diving watch” and meets the requirements of the ISO6425 standard, doesn’t mean it’s thick and heavy. The proof? The 11mm thick Calibre Diver de Cartier is not only slim and sophisticated but also has all the required assets for use in deep water: waterproof (up to 300m), readable (Super LumiNova features on the dial) and reliable (unidirectional rotating bezel and screw-down crown). Available in steel or rose gold, the 42mm case houses the 1904MC automatic movement made by Cartier which brings to life the hour, minute and small second hands at 6 o’ clock on the dial and the 3 day date display at 3 o’ clock. In keeping with the Calibre collection’s design, the Diver has a black dial whose upper half has a blue tint surrounded by Roman numerals with the famous oversize XII. Price: 25,300 CHF (red gold on rubber) and 7,400 CHF (steel on rubber)
