"Gas switches" is how many different mixes this computer can be programmed to switch between mid-dive, mostly relevant for technical/staged-decompression diving. It doesn't tell you which gas types (air, nitrox, trimix) are supported. See Gas types and the product description above for that.

  • Rechargeable only, no field-swappable battery
Diver community sentiment
Mostly positive

Divers discussing the Nautic S (a December 2025 release) consistently single out its AMOLED display as a genuine upgrade, bright, colorful, and easy to read underwater, and several note that air integration and dive features come at a notably lower price than comparable Shearwater or Garmin computers. Recurring gripes center on the button/menu logic feeling unintuitive when switching from other brands, and on lingering distrust of Suunto stemming from past customer-service complaints and the company's acquisition by a Chinese owner, which pushed at least one longtime user toward Shearwater instead. Because the product is very new, long-term reliability is still an open question rather than a settled complaint.

The Nautic S is Suunto’s newest dive-focused wearable, launched in December 2025, stripping out general smartwatch/sports-tracking features to focus on diving with an AMOLED display, GPS, and wireless air integration. It sits below the sports-watch-hybrid Suunto Ocean in Suunto’s current lineup.
