Built for extremes

The Samsung Galaxy Watch Ultra (2025) in Titanium Silver is a 47 mm LTE smartwatch with a 1.5 inch Super AMOLED display and 64 GB storage. It runs Wear OS Powered by Samsung and includes an extensive sensor suite for health and environmental tracking. The titanium case measures 47.4 by 47.1 by 12.1 mm and weighs 60.5 g.

Who this suits

Athletes and outdoor adventurers who want standalone connectivity, multi-band GNSS, and up to 100 hours of battery life in power-saving mode will benefit. Buyers who need a smaller or lighter watch for daily comfort, or who prefer a traditional round bezel without the protruding sensor housing, should consider other models.

Deciding specification

The 590 mAh battery delivers up to 80 hours of typical use with the always-on display off and up to 60 hours with it on, which is the longest endurance yet in the Galaxy Watch line.

Questions about this item

Does the 47 mm case require a specific band width that differs from standard watch straps?

The watch uses a 47 mm case with a supplied Medium/Large Marine Band designed for its integrated lug system; third-party straps must match this mount.

Can the LTE model operate independently for calls and data while my paired phone is powered off or left at home?

Yes, the embedded eSIM supports 3G WCDMA and 4G LTE across multiple bands so the watch can make calls, stream music and receive notifications without the phone nearby.

How can I verify that the watch is recording heart-rate, GPS and sleep data correctly after the first setup?

Open Samsung Health on the watch or phone; live heart-rate, GPS track maps and the morning Energy Score with sleep stages will appear once sensors have calibrated during initial workouts and nights.
