Why I Tested the Ultra 2

I already own the Apple Watch Ultra 2 for daily use, so I've tested it on cold water wetsuit dives as well as warm water dives in Fiji 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. It is not intuitive from a user interface perspective when it comes to button/crown presses. Also the button/crown would accidentaly get pressed underwater when it rubbed up against other items on my wrists. Highly annoying and potentialy dangerous.


Performance in the Water


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.
