Buying decision

Should you buy it?

Buy the Galaxy Watch Ultra2 if you have a Galaxy phone and want a rugged Wear OS watch: Samsung lists it at $699.99 (Oct 8, 2026). Reviewers praised its exceptionally bright AMOLED, dual-frequency GPS accuracy and better battery life, and Samsung rates it for up to 60 hours with the always-on display. Skip it if you have an iPhone, because it won't pair, or small wrists, since it comes in one 47mm size. Some health features need a Samsung phone.

Best for

Galaxy phone owners who hike, run or dive and want Samsung's toughest, longest-lasting watch.

Not for

iPhone users and anyone with small wrists.
