The CressiSub Cartesio impresses with its extremely compact and aerodynamic design. It features a completely flat profile case that minimizes water resistance and prevents snagging on ropes or marine vegetation. Its display is protected by an exceptionally hard mineral crystal, which offers top protection against scratches and impacts, while being surrounded by a sturdy stainless steel bezel that gives it a premium feel and durability.

The digital display of the Cartesio incorporates Cressi's innovative UFDS (User Friendly Display System), which offers unparalleled clarity. The digits are large and bold, organized in such a way that the most important information (depth, time, decompression) stands out immediately. The integrated high-performance backlight ensures that the watch remains perfectly readable even in the darkest underwater environments or during night dives.

On the technical side, the watch uses the advanced Cressi RGBM algorithm (developed in collaboration with Bruce Wienke), which ensures safe decompression calculations for repetitive multi-day dives. In Scuba mode, it fully supports the use of air as well as Nitrox with the ability to adjust the oxygen mixture from 21% to 50% and the partial pressure (PO2), providing the diver with all the necessary data for a fully controlled dive.

The CressiSub Cartesio is the ideal companion for freediving and spearfishing enthusiasts thanks to the special Free Mode. The software accurately records the current depth, dive time, and number of dives, while as soon as you surface it immediately displays the surface time timer. In this way, the diver can precisely monitor the recovery time of their body before the next underwater attempt.

The Cartesio is waterproof up to a depth of 120 meters and features a spacious digital logbook for storing your dive history. Its battery offers great autonomy, while the software includes a smart power-saving mode when the watch is out of the water. Thanks to the durable rubber strap and its sleek, compact design, it can be worn with the same comfort as a sporty, everyday watch with high aesthetics for all your activities.
