Why I Tested the Ultra 2
I already own the Apple Watch Ultra 2 for daily use, so I tested it on a cold water wetsuit dive just to see how it handled. With the Oceanic+ app, it functions reasonably well as a basic depth and time tracker, but that’s about where its utility ends. It’s sleek and modern, but missing essential diving features. I wouldn’t recommend it to anyone who doesn’t already own the watch—and certainly not as a primary computer.
Performance in the Water
- Screen & Visibility: Bright and easy to read, but button control is awkward with gloves.
- Data & Features: Depth, time, NDLs, and ascent alerts—but no air integration, RMV, compass, or dive planning.
- Navigation & Interface: The app is visually clean but not optimized for underwater use in cold water.
- Durability: Hardware feels solid, but it’s not a replacement for a purpose-built dive computer.
- Battery: Good for a single dive, but won’t last multiple dives without a recharge.
Comparisons
Shearwater Perdix 2 AI
- Fully customizable and rugged
- Air integration, cold water capable, glove friendly
- Serious tool for progression
Mares Genius
- More focused on diving, with air integration
- Outdated software, but still a better option for real dives
Verdict
If you already own the Apple Watch Ultra 2, the Oceanic+ app makes it usable for very casual recreational dives—like a guided reef tour on vacation. But it’s not something I would ever purchase solely for diving. It lacks air integration, has minimal customization, and isn’t built with serious dive reliability in mind. I only carry it as a backup when traveling warm, and even then, it’s for convenience—not trust.
Would I buy it again for diving? No.
Would I dive with it if it’s all I had? Only on an easy, warm water guided dive.

Deep Dive Score Explanations
- Function & Performance – 5.5: Basic functionality. Lacks gas data, planning tools, or diving redundancy.
- Ease of Use – 6.0: App is modern but not glove-friendly. Requires subscription.
- Versatility – 5.0: Tropical wetsuit diving only. Not suitable for cold or drysuit dives.
- Durability & Build – 6.5: Strong for a smartwatch, but not a dive-specific build.
- Value – 5.0: Only makes sense if you already own the watch. Not worth buying for diving alone.
- Brand Trust – 6.0: Oceanic is established, but Oceanic+ is not a serious contender in this category.
