I would not buy this watch. After diving with 11 guys for a week the best answer is a the Apple Watch Ultra. The Apple Watch Ultra can function as a dive computer using the built-in Depth app and the Oceanic+ app. The Depth app automatically launches when submerged and tracks depth, time, and water temperature, while the Oceanic+ app provides more advanced features like dive planning and decompression information, requiring a subscription for full functionality. Just works!
