Cressi Donatello Dive Computer
A large, easy-to-read Cressi dive computer built for straightforward recreational scuba, Nitrox and freediving without unnecessary menu complexity.
As you evaluate options for the best dive computer for entry-level recreational diving, the Cressi Donatello stands out as a practical, modular wrist instrument engineered for those who want straightforward reliability. At the core of its design is an intuitive single-button interface that makes switching between Air, Nitrox, Gauge, and Free modes effortless. The device features a wide User-Friendly Display System (UFDS) with an edge-to-edge high-definition screen, extra-large numerical digits, and clear contrast proportions. All information is separated by light lines to ensure quick readability, even during stressful or emergency situations.
Performance-wise, this model incorporates the Cressi RGBM algorithm with Deep Stop capabilities, a salt-water-calibrated depth gauge mode, and complete Nitrox management. Practical usability is further enhanced by an automatic backlit display, clear audible alarms, and a visible battery life indicator. Powered by a user-replaceable CR2430 button battery, the unit also supports post-dive data tracking by linking to iOS and Android devices via an optional Bluetooth interface and the Cressi app.
When considering the best dive computer for beginners, the Donatello delivers essential functionality without unnecessary complexity.
- Best for: Beginner through recreational divers, traveling divers, freedivers and photographers who prioritize a large, simple display.
- Main advantage: High-contrast screen with extra-large numbers and uncomplicated controls.
- Compatibility: Standalone wrist computer; no camera, housing, port or lighting compatibility restrictions.
- Useful differentiator: Dedicated Free/Apnea mode in addition to Air, Nitrox and Gauge modes.
- Connectivity: Dive-log transfer requires the optional Cressi Bluetooth interface rather than having Bluetooth built into the computer.
- Tradeoff: It does not target divers wanting built-in air integration, an integrated compass, a color screen or advanced multigas technical features. The device is powered by a long-lasting CR2430 button battery which can be replaced by an authorized Cressi center by verifying perfect watertightness.
Cressi Donatello Quick Specs
Key Donatello Features in Real Diving
A Display You Can Read While Managing a Camera
Underwater photographers already divide their attention between buoyancy, a subject, exposure settings, strobes and their buddy. The Donatello's large numerical display makes a quick depth or NDL check easier than on many smaller watch-style computers.
- Extra-large numerical readout
- High-contrast screen
- Backlight for dark water and night dives
- Current time remains available during a dive
Air, Nitrox and Repetitive-Dive Management
For resort trips and liveaboards, the Donatello tracks the information that matters between repetitive dives: surface time, desaturation and no-fly information. Nitrox can be configured up to 50% oxygen with adjustable PPO2.
- Cressi RGBM decompression algorithm
- Adjustable safety-factor settings
- Safety-stop and ascent monitoring
- CNS oxygen toxicity indicator
A Real Freedive Mode, Not Just a Bottom Timer
Divers who mix scuba with freediving get a dedicated apnea program that tracks individual dives, surface intervals and the overall session. That makes the Donatello more flexible than basic scuba-only computers.
- Depth, temperature and dive-time tracking
- Surface-interval tracking
- Depth, time and recovery alarms
- Off mode disables dive sensors for swimming or snorkeling
Cressi Donatello vs. Mares Puck 4, Suunto Vyper Novo & Cressi Da Vinci
These dive computers solve different problems. Choose based on the features you will actually use underwater rather than the longest specification sheet.
| Product | Algorithm / Capability | Display / Interface | Connectivity / System | Best Use |
|---|---|---|---|---|
| Cressi Donatello | Cressi RGBM; Air, Nitrox to 50%, Gauge, Free | Large high-contrast display; simple control | Optional external Cressi interface; no air integration listed | Beginner/recreational scuba, freediving, travel, photographers wanting fast readability |
| Mares Puck 4 | Bühlmann ZH-L16C with customizable gradient factors; up to 3 gases | 800-segment display; single-button interface | Built-in Bluetooth to Mares / SSI apps; no air integration | Divers wanting a simple computer with more decompression customization and built-in connectivity |
| Suunto Vyper Novo | Suunto RGBM; Air, Nitrox, Gauge, Free; multigas capability | Matrix display with digital compass | Optional wireless tank-pressure integration; USB/DM5 ecosystem | Divers wanting compass and transmitter support in an older-generation recreational computer |
| Cressi Da Vinci | Bühlmann ZHL-16C; up to 4 programmable gas mixes | 1.54-inch full-color TFT; two-button navigation; compass | Built-in Bluetooth with DiveSync; rechargeable battery | Divers wanting a modern color display, compass, wireless syncing and more room to progress |
Bluewater tip: If built-in Bluetooth and adjustable Bühlmann gradient factors matter more than freediving, look closely at the Puck 4. If you want Cressi's color display, compass and more advanced gas management, the Da Vinci is the stronger upgrade. Vyper Novo availability may vary because it is an older-generation Suunto platform.

Cressi Donatello FAQ
Is the Cressi Donatello a good dive computer for beginners?
Yes. Its large display, straightforward controls and recreational Air/Nitrox features make it a strong option for divers who want essential information without a highly complex interface.
Can the Cressi Donatello be used with Nitrox?
Yes. The Donatello supports oxygen-enriched mixtures up to 50% O2, with PPO2 configuration from 1.2 to 1.6 bar. Use Nitrox only within the limits of your training and certification.
Does the Cressi Donatello have air integration?
No wireless tank-pressure integration is listed for the Donatello. You should continue monitoring cylinder pressure with a separate SPG or compatible pressure instrument.
Will the Donatello work with my underwater camera and housing?
Yes from a dive-computer standpoint because there is no electronic connection between the Donatello and your camera system. Camera, housing, port, lens and lighting compatibility must still be checked separately.
Can I download dives from the Cressi Donatello?
Yes, but the Donatello does not have built-in Bluetooth. Cressi offers a separate interface for transferring and viewing compatible dive-session data.
Can I replace the Donatello battery myself?
Cressi's technical specifications identify the device is powered by a CR2430 button battery that must be replaced by an authorized Cressi center to ensure perfect watertightness is verified.
Does the Cressi Donatello work for freediving?
Yes. Its dedicated Free/Apnea mode tracks depth, dive time, temperature, dive count, surface intervals and configurable apnea alarms.
How does the Donatello compare with the Mares Puck 4?
The Donatello is attractive if you want dedicated freediving and Cressi's simple large-display interface. The Puck 4 is the stronger choice if built-in Bluetooth, Bühlmann ZH-L16C with customizable gradient factors and up-to-three-gas capability are higher priorities.
