Is the Ultra 3 worth it over the Ultra 2?

If you want satellite messaging, a brighter wide-angle display, or the longer battery life, yes. Owners of the Ultra 2 with good battery have little else to gain.

How long does the battery last?

Apple rates it at up to 42 hours of normal use and up to 72 hours in Low Power Mode. Heavy GPS workouts cut that to roughly a day.

Can I use it without an iPhone?

No. The Ultra 3 runs watchOS and needs an iPhone to set up and pair. Cellular service also requires a carrier plan.

Is it good for swimming and diving?

Yes. It is water resistant to 100m and rated for recreational diving to 40m, plus high-speed water sports.

The watch, the Alpine Loop band in the chosen size, and a magnetic fast-charging USB-C cable. A power adapter is not included.

The best new price was $549 at Best Buy as of November 6, 2026, down from the $799 launch price. Watch for discounts around major sales events.

Our take on the Apple Watch Ultra 3

The Apple Watch Ultra 3 is Apple's largest, toughest watch: a 49mm natural titanium case, sapphire crystal, and 100m water resistance. It adds satellite messaging for emergencies, a brighter wide-angle display, and up to 42 hours of battery (72 in Low Power Mode). At $549 at Best Buy as of November 6, 2026, it sits well below its $799 launch price, making this the cheapest the Ultra has been new.

What reviewers say

Owners praise the Ultra 3 as a durable, long-lasting adventure watch with accurate GPS and a screen that stays readable in sunlight. Most criticism centers on its size and weight and on the extra cost of cellular service.
