Cressi's Donatello is an underwater and freediving computer. It is ideal for other water activities, thanks to the deactivation option of the "dive" functions, that avoids unnecessary alarms while snorkeling or swimming Donatello has a high contrast display for excellent view even in bright sunlight. The heavy-duty case with a steel button is fitted with a bezel which, like the case, is plastic made. The computer has an underwater resistance is up to 393' (120m). The two-tone wrist band is made of thermoplastic urethane (TPU) rubber with a stainless-steel buckle.

High contrast display with extra large numbers and easy access menu. 12/24 clock time format with calendar and high-power backlit display for low light and night dive conditions. Computer also provides surf time, desaturation and no fly time calculator and lets you know when battery needs replacing with a low battery icon. The computer can be set for imperial or metric measurement units. The algorithm is the Cressi- Wienke RGBM for complete diving data processing When in the Scuba mode Donatello can be set for air or nitrox with a PPO2 1.7 psi-23.2 psi (1.2 bar-1.6 bar) configuration. Computer allows mixes of 21% to 50% oxygen. Graphic indicator of CNS toxicity level of oxygen, safety stop indicator, multiple level safety factor configuration, altitude configuration to 12,140' (3,700m) and an algorithm for managing uncontrolled ascents are other features of this versatile diving instrument. Suitable for repeated, multiday decompression. Visualization of time while diving, add / remove deep stop, alarm in case of breach of ascent speed, decompression or PPO2, ability to disable the ascent alarms, planning scroll function of no-decompression limits, maximum dive depth alarm and ability to perform a total reset, which is useful for rental purposes.

When used in the freediving (apnea) program computer display's all diving parameters of depth, temperature, dive calculator, maximum dive depth alarm, dive time, length of surface interval between each dive, length of diving session, depth, dive time and surface interval alarms, recovery time alarm and visualization of time at dive phase.

When in the Gauge program (without decompression calculator) the Donatello provides depth/temperature indicator, average depth, dive time in minutes and seconds, has a resettable depth stopwatch and a visualization of time at dive phase. All information in all modes is logged with a memory of up to 50 dives in per category. Computer has a replaceable protective display screen and a user replaceable CR2450 battery. Optional Interface of diving profile is available. Comes with an owner's manual and is available in multiple colors.
