The only design element that does not square with the diver aesthetic are the sword hands, which could be broader. The bezel is matched by the tone of the dial, both have a black piano-like finish, which is attractive and difficult to capture in photos. An important detail is the ADLC coating on the bezel, which gives it a durable, glossy black finish ADLC is scratch-resistant. Visually the Calibre de Cartier Diver looks like the luxury sports watch it is. These tests include applying a 200 N to the spring bars on each side of the watch, to ensure the strap or bracelet will not snap off inadvertently.

The watch was also designed to pass all the other ISO 6425 tests, including a water resistance test to 375 m for one minute and a thermal shock test, whereby the watch is immersed in 30 cm of water for 10 minutes each at 40 ☌, 5 ☌ and then 40 ☌ again. The Cartier secret signature is integrated into the “X” numeral Fitted with a 2.2 mm thick crystal (compared to 1.2 mm in the regular model), the Calibre de Cartier Diver is water-resistant to 300 m (ISO 6425 mandates a minimum of 100 m), but that is just the basic criteria. And though Cartier does not explain the reason for its use, the system was likely adopted so as to allow a screw down crown to be integrated into the normal Calibre de Cartier case (which normally has a friction fit crown). This unusual system was originally developed for the Tortue Monopusher chronograph, in which the crown had to serve as the time-setting mechanism as well as chronograph pusher. The crown is topped with Cartier’s signature blue cabochon, somewhat incongruous in a dive watch Here the screw-down crown is connected to the tube, with the threads located inside the tube, which gives this better reliability according to Cartier. Unlike conventional crowns where the crown is connected to a stem, which is inside the tube fixed to the case, the Calibre de Cartier inverts the construction. Another notable case detail lies in the crown. That is equivalent to a decade’s worth of wear, and the bezel still turned with the same smoothness after the test. Just to ensure the bezel worked as envisioned, Cartier tested this bezel submerged in water – with salt and sand thrown in – for two turns per second for an hour and a half, which equals 10,800 turns. The inner coating means the bezel is self-lubricating, since ADLC is virtually frictionless. The form of the teeth and studs were optimised to give the bezel the right sound and feel.Īnd the bezel is coated with amorphous diamond-like carbon (ADLC) on the outside, hence its black colour, and also on the inside. Significant effort was put into ensuring the bezel is not just reliable and robust, but also to give it a good tactile feel.Ĭomprised of two parts – the upper bezel with the engraved numerals and the notched outer ring – the bezel turns in one direction with 120 precise-sounding clicks, thanks to teeth on the underside of the bezel and studs on the case below. Though found on every dive watch and typically simple in construction, the bezel on the Calibre de Cartier Diver is anything but. The dive version, however, is distinguished by its unidirectional bezel, one of the key criteria of the ISO 6425 standard (which refers to it as a “time-preselecting device”). Based on the Calibre de Cartier, the diver’s version of this model uses the same basic case form, making it similar to last year’s Calibre de Cartier Chronograph. Meeting these requirements means the watch can be considered a diver’s watch suitable for scuba diving. It was designed to conform to ISO 6425, a standard for dive watches. ISO 6425 is price- and brand-agnostic, and includes water, shock and temperature resistance. While Cartier has made sport watches before, the Calibre de Cartier is its first true dive watch. Equipped with the 1904 MC movement, the Calibre de Cartier Diver is water resistant to 300 m, and was designed according to the ISO 6425 standard for scuba diving watches.
