Is the Apple Watch Ultra 3 suitable for scuba diving?

Yes. The Ultra 3 supports scuba diving with the Depth app and is engineered for diving down to 40 meters under tested conditions. For serious diving, follow dive guidelines and check accessory/third-party dive computers for advanced scenarios.

How long does the battery last during continuous outdoor workouts and GPS use?

Apple quotes up to 42 hours of regular use and up to 72 hours in Low Power Mode. For continuous outdoor workouts with full GPS and heart rate in Low Power Mode, Apple also reports extended continuous tracking (specific durations can vary by settings—see Apple’s product notes).

What’s the difference between Natural Titanium and Black Titanium?

The materials are both aerospace-grade titanium; Natural Titanium has a lighter, raw titanium finish while Black Titanium has a darker, space-black titanium coating/finish for a different aesthetic. Functionally they’re the same hardware. Band options and sizes may vary by color and region.
