The philosophy of the CressiSub Leonardo is based on simplicity, achieved through the innovative Single-Button Interface system. A single central button is enough to navigate all menus, change settings, and program your dive parameters. This intuitive design eliminates complexity, allowing you to operate the device with maximum ease, even when wearing thick diving gloves, avoiding mistakes during preparation.

The watch features an impressively large High Definition LCD screen, which integrates the PCD (Priority Display Control) system. This technology organizes information based on its importance, displaying the current depth, dive time, and decompression limits in large, easy-to-read digits. For dives in low-light conditions, the built-in backlight is easily activated, ensuring excellent visibility in any environment.

Your safety underwater is protected by the advanced Cressi RGBM algorithm, developed in collaboration with the leading Bruce Wienke. The algorithm performs continuous calculations for safe decompression during repetitive dives over multiple days. The Leonardo fully supports the use of enriched air Nitrox with oxygen concentration from 21% to 50%, allowing you to set the maximum partial oxygen pressure (PO2) for greater safety.

The CressiSub Leonardo easily adapts to different types of activities, featuring three main modes: Air for traditional diving, Nitrox, and Gauge for use as a depth gauge and timer. It is equipped with a comprehensive system of acoustic and visual alerts, which immediately warn you if you exceed the allowed ascent rate or approach decompression limits, ensuring compliance with safety rules.

Designed and manufactured at Cressi's factories in Italy, the Leonardo stands out for its robustness and is waterproof to a depth of up to 120 meters. It features a spacious digital logbook with a recording capacity of up to 50 hours or 60 dives. Its battery (CR2430) offers long autonomy and has a battery life indicator on the display, while it can be easily replaced by the user without the need for specialized technical equipment.
