Call for Price

After the successful Leonardo, Giotto, Newton, Drake and Goa, Cartesio is the sixth project designed, developed and 100% produced in Italy by Cresi's subsidiary Cressi Elettronica. It is a watch-sized dive computer of completely modular construction, extremely robust and reliable. Cressi has all the quality control of this product because it is entirely developed and manufactured in Cressi Elettronica, both in terms of software programming and in its construction and manufacture, quality control and after-sales service.

ScubaLab Watch-Style Dive Computer Best Buy 2018
Testers appreciated the Cressi Cartesio's sensible two-button navigation (with short presses to toggle and long to select or back out), and scored it very good for intuitive operation. Many testers, especially female divers, also liked its compact size, which doesn't look out of place on smaller wrists. The high-contrast display with large characters tied top score for ease of reading on the surface, even in direct sun, and was rated good underwater.

Under its modern and attractive design hides a complete dive and apnea computer that stands out for its versatility. Suitable for the advanced diver, or for technical diving, and for apnea or snorkelling, but surprisingly simple for the average diver by providing information clearly and simply with just two buttons.

Colours: Available in Black, Black Metal or Copper.

Cressi Cartesio Dive Computer Features

  • Anti-impact technopolymer case. This composition allows a great lightness, resistance to the blows and to the aesthetic aging. The computer case is extremely flat, with a very hydrodynamic cornerless section and its dimensions are relatively contained, with a vision of the model digits.
  • Extra-flat profile (maximum height 14 mm) with a completely rounded design, very hydrodynamic and avoids possible snagging. Even the anchorage of the strap follows the profile of the box.
  • Two highly integrated low-profile push buttons with the minimised backlash to ensure that the O-rings are watertight when working perfectly perpendicularly and to prevent the entry of particles or small grains of sand that could block them.
  • Case diameter only 48 mm.
  • Large screen UFDS (User Friendly Display System) 38 mm in diameter vs 48 mm total box. The distribution of the information, screen contrast, proportions and size of the digits have been studied to facilitate the reading. All data are segmented with slight separation lines that facilitate reading even in a stressful or emergency situation.
  • New high-performance, low-power processor. It allows much faster data processing, more power backlighting and sound alarms and doubles the battery life compared to previous models. CPU ARM Cortex M3 32 bit | Frequency 14 MHz | Flash Memory 256 Kb | 32 Kb RAM
  • High intensity backlit display by push-button or in case of alarm (5 seconds per push)
  • High-strength mineral crystal display.
  • Guaranteed resistance up to 120 m depth.
  • Optional Bluetooth interface.
  • Thermoplastic rubber strap with stainless steel buckle.
