Bottom Line
Choose it for rugged Samsung perks like long battery life, LTE, and a bright big display. Skip it if you want a smaller watch, sharper value, or top-tier tracking accuracy.
Best for
Samsung users who want a big rugged smartwatch with LTE, strong battery life, bright outdoor readability, and broad workout support. It also makes the most sense for people who value the 64GB storage bump for offline content.
Not for
Anyone who wants a smaller case, the best launch-day value, or sports-watch-level sensor accuracy. If you already own the 2024 Ultra, several reviews suggest the 2025 version is only worth it for the extra storage, color, or immediate software refresh.
Verdict
Samsung’s 2025 Galaxy Watch Ultra is still a strong premium Android smartwatch, especially if you want Samsung’s biggest display, standard LTE, rugged titanium build, and some of the best battery life in the company’s lineup. It also benefits from the newer software features, broad workout support, and strong customization. The tradeoff is that this refresh feels incremental. Multiple reviews say the new model is hard to justify at launch price because the 2024 Ultra remains so similar, and the scientific review still places its health and GPS accuracy in the good-enough tier rather than the very best. For the right Samsung user, it works well; for bargain hunters, it is a tougher sell.

Blood oxygen tracking is widely available as part of the sensor package, but one long-term review says the SpO2 readings tend to run low, so confidence in the metric is mixed.
-
Navigation is serviceable and helped by touch and haptics, but several reviews still miss a true rotating control or want better workout-time interactions.
-
Sleep tracking is useful but mixed: some reviews call the stages relatively accurate, while others say certain sleep metrics still miss obvious awake time.
-
Wellness features like Energy Score, guidance, and metric explanations add context, but some reviewers feel parts of the insight layer are generic or gimmicky.
-
Setup and app integration are smooth, but Samsung’s split between Galaxy Wearable and Samsung Health remains a mild annoyance.
