How is the Ultra2 different from the original Galaxy Watch Ultra?

The main changes are battery and screen: the Ultra2 has an 800mAh battery with about 40% more usage time, and a 1.52-inch Super AMOLED panel rated up to 5,000 nits. The rugged 47mm titanium build and dive features carry over.

Yes. It is EN13319-certified and runs the Mares dive computer app, with ascent and descent monitoring, depth-limit alerts, safety stop info and speed monitoring. That covers recreational diving, not technical or mixed-gas diving.

Does it work with an iPhone?

It pairs, but many health features and Samsung apps need a Galaxy phone, and blood pressure and ECG support varies by region. For full functionality, use it with a recent Samsung handset.

What health sensors does it have?

Heart rate, ECG, bioelectrical impedance (BIA), blood pressure, sleep tracking and a vitals overview. Blood pressure and ECG require calibration and regional approval.

How long does the battery last?

Samsung rates the 800mAh battery at about 40% more usage time than the original Watch Ultra. Real endurance depends on LTE use, always-on display and GPS workouts, which drain it fastest.

The watch, a charging cable and quick-start documentation. A charging brick is not included.

Our take on the Samsung Galaxy Watch Ultra2 47mm

The Galaxy Watch Ultra2 is Samsung's flagship rugged smartwatch, a 47mm titanium-cased Wear OS watch built for outdoor training and water sports. Its 1.52-inch Super AMOLED screen reaches up to 5,000 nits, so it stays readable in direct sun, and the 800mAh battery is rated for roughly 40% more use time than the original Watch Ultra. Health coverage is broad: heart rate, ECG, BIA, blood pressure, sleep and vitals, plus a Mares dive computer app with EN13319 certification for recreational diving. It competes with the Apple Watch Ultra and Garmin's adventure watches: it matches them on screen brightness and diving features, and beats most rivals on battery life, though iPhone owners lose much of the health and app integration.
