The Suunto Nautic S dive computer is a wrist-mounted dive computer built for both recreational and advanced divers. Known as a reliable dive computer, it integrates core scuba and freedive functionality with smart navigation and gas-management support. It’s especially suited for divers who want a compact wrist device that supports wireless tank-pressure integration via the Suunto Tank POD compatibility.
If you’re looking for a full-featured dive computer rather than a sport watch hybrid, the Nautic S provides a strong option—though if you require deep technical diving features (e.g., CCR support or extended trimix modes) you may need to verify future firmware updates or consider a more dedicated technical model.
- A high-performance dive computer wristwatch that supports wireless tank-pressure monitoring, single- and multi-gas modes, and sidemount configurations.
- Best for divers who want a compact and capable wrist computer designed by Suunto, focused on diving and freediving rather than full smartwatch features.
- Key compatibility: works with Suunto Tank POD for wireless gas-pressure integration, supports sidemount and freedive modes.
- Limitation/gotcha: Depth rating for diving is specified up to 80 m, while water-resistance of the watch case is 100 m—verify technical diving requirements.
- Requires firmware updates and Suunto app to access full logging, GPS/route functions, offline maps and dive-log sharing.
