This is an incredible achievement, given that the water resistance of the Calibre de Cartier Diver is ten times that of the base model. The case, available in stainless-steel or 18-carat red gold, has the same 42mm diameter as the Calibre de Cartier base model, with its satin-finished surfaces with polished edges, and is a mere 1 millimetre thicker than it.

Yet the watch remains astonishingly slender. the small seconds counter) have to be visible in total darkness at a depth of 25 metres.Ī screw-in case back, oversized seals, a screw-in crown (set with a faceted synthetic spinel) and a thick sapphire crystal ensure water resistance to 300 metres. In order to meet the requirements of ISO 6425 the time and running indicator (i.e. Note also the discreet Cartier signature on one of the bar’s of the X in the 10 o’clock position and the “L Swiss Made L” indication below the small seconds counter to indicate the use of photoluminescent material on the dial. It is also highly resistant, since it is made of Amorphous Diamond-Like Carbon (ADLC).Ĭartier’s signature Roman numerals still feature on the dial, although the luminescent coating is only applied to the hour markers, the oversized XII and the small seconds counter at 6 o’clock, which gives the watch two distinct “faces” – one for daytime and one for night-time. But particular attention has been paid to the sound of its clicks, to make them both more acoustically appealing and at the same time more audible.

The unidirectional returning bezel, for example, has been designed with 120 teeth to allow adjustment to within half a minute, like that of similar diver’s models. In the style typical of Carole Forestier Kasapi, who won the best watchmaker award at the Geneva Watchmaking Grand Prix in 2012, novel approaches have been found for even the most mundane of functions in the Calibre de Cartier Diver. The challenge for Cartier’s watchmakers was to produce a diver’s watch that meets all the eight criteria for legibility and resistance required by the ISO standard 6425 with the familiar design codes of the brand.
