The Samsung Galaxy Watch Ultra 2 refines its predecessor with a brighter display, larger battery, and a more comfortable, lighter design. Priced at $700, it targets rugged, outdoorsy users with enhanced health tracking and new features like Trail Run mode and hydration guidance.

The Ultra 2 boasts a display that reaches 5,000 nits, up from 3,000, and a slightly larger 1.52-inch screen. The most significant upgrade is the 800mAh battery, a 35% increase over the original. It's also 12% thinner and 25% lighter, with refined buttons for better usability.

New health features include the Vitals collection and updated Daily Cardio Load and Heart Health scores. The Trail Run mode offers detailed metrics, and hydration guidance expands on the Sweat Loss feature. For divers, collaboration with Mares adds ascent/descent assistance, available via an exclusive Diving app later this year.

While the antioxidant test feature is noted as potentially flawed and sensitive to skin tone, the watch excels at basic smartwatch functions and navigation. The bright screen aids readability, and features like compass-based tracking proved useful during a hike. Despite competition from devices like the Apple Watch Series 9, the Ultra 2 offers unique health and diving-specific functionalities.
