After the successful Leonardo, Giotto, Newton, Drake, and Goa, the Cartesio is the sixth project designed, developed, and produced in Italy by its subsidiary Cressi Elettronica.
It's a computer with a watch design and completely modular construction, extremely robust and reliable. Cressi is particularly keen on quality, in fact, this product is entirely prepared and manufactured in Cressi Elettronica, both as regards software programming and for its production and manufacturing, quality control, and after-sales service.
Under its latest and attractive watch appearance is hiding thorough software which highlights its versatility. It's perfect for advanced divers or technical diving and for apnea or snorkeling, but surprisingly simple for medium divers because of the clear and easy information supply only with two buttons.
CONSTRUCTION
- Anti-impact technopolymer case. This composition allows great lightness, resistance to the blows, and 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 pushbuttons with a minimized 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 is 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 | Frequency14 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 (sold separately).
- Thermoplastic rubber strap with stainless steel buckle.
GENERAL SPECIFICATIONS

- Clock 12/24 hours with calendar and seconds.
- Precision chronometer.
- Alarm Clock.
- High-intensity backlight function (4000 Mlux, more than twice the number of computers with the highest illumination power to date).
- Indication of no-fly time and desaturation time.
- Low battery indicator.
- Metric or imperial units.
- User-replaceable battery.
- OFF MODE for use in snorkeling/swimming.
- LOGBOOK with the historical memory of 50 dives per mode or 40 hours
- Air, Nitrox (EAN), Gauge, and Free modes.
- Extremely long battery life through a combination of systems: economy mode when not using the computer with automatic start and a new low-power processor. CR2450 Battery
- Dive Session Software Interface with connection to the dive computer simply supports the computer and connection to the PC with the USB cable. The software is compatible with all Windows and Mac versions.
- Depth gauge calibrated in salt water for maximum accuracy in the most common use.
- Possibility of deactivating DIVE functions to avoid unnecessary alarms during snorkeling or swimming
DIVE MODE
