Suunto Ocean Steel Black

Suunto Ocean Steel Black — the dive computer + sports watch that does it all

A single device for all your adventures, underwater and on the surface. Suunto Ocean Steel Black combines full dive computer and multisport watch functions with a 1.43″ AMOLED display of high clarity, wireless air integration, underwater route tracking and advanced outdoor capabilities. All managed and shared via Suunto App.

Best underwater performance

• Dive modes for air and nitrox, with multi-gas option (up to 5 gases).
• Suunto Bühlmann 16 GF algorithm with adjustable Gradient Factors to personalize decompression.
• Wireless air integration with Suunto Tank POD: check tank pressure, gas consumption and remaining gas time on your wrist (supports multiple cylinders).
• Freediving with dedicated surface/subsurface views and configurable alarms (depth, time, ascent/descent rate, etc.).
• Underwater route tracking: records your dive path combining surface GPS and internal sensors (accelerometer, gyroscope, magnetometer and pressure) and lets you replay it in 3D in the app after the dive.
• Operating depth for diving: up to 60 m (compliant with EN 13319).

🔧 Important note

The underwater route is not shown on the watch during the dive: it syncs and displays in Suunto App afterwards. For an accurate route, activate GPS on the pre-dive screen and wait for a green signal lock.

🔧 Important note

Air integration requires Suunto Tank POD (sold separately). Connect one POD per cylinder to view pressure, consumption and gas time.
