Is the Galaxy Watch Ultra2 right for you?
The Galaxy Watch Ultra2 is Samsung's watch for outdoor and water sports. Its 47 mm titanium case carries 10ATM water resistance, IP69K protection against high-pressure water jets, MIL-STD-810H, and EN13319 certification as a diving instrument, which none of Samsung's other 2026 watches have.
It also has the largest battery and brightest display in Samsung's lineup: 800 mAh, which Samsung says is 35% more than the previous Ultra, and a 1.52-inch sapphire screen rated up to 5,000 nits at localized peaks. Every model includes LTE.
The cost is weight and price. At 61.5 g it weighs nearly twice as much as the Galaxy Watch9, it comes in one size, and it launched at $699.99 in the US. Like the Watch9, it cannot be activated with an iPhone.
A good fit if
- You need a watch with documented EN13319 dive-instrument certification. Confirm Samsung's operating limits and required app availability for your activity before buying.
- You want LTE and the largest battery Samsung offers in a watch.
- You prioritize a higher listed peak display brightness over the Watch9's lower weight.
Look elsewhere if
- You want a light watch for sleep tracking and daily wear: the Galaxy Watch9 weighs 31.5 to 34.0 g.
- You have a smaller wrist: the Ultra2 comes only in 47 mm.
- You use an iPhone.
Which configuration to choose
There is a single configuration: 47 mm with LTE, 2 GB of memory, and 64 GB of storage, so the only choice is the band and color. If you do not need its dive certification or tougher build, the Galaxy Watch9 offers the same processor, sensors, and software at a lower launch price.
