Built for the extremes. The Samsung Galaxy Watch Ultra 2 is Samsung's 2026 rugged flagship smartwatch — the watch for outdoor athletes, divers, trail runners, cyclists, and serious health trackers who need more than the Galaxy Watch 9 can offer. Announced July 22 at Galaxy Unpacked London, releasing August 7, 2026. The Ultra 2 upgrades almost every important specification over the original Ultra: a significantly brighter 5,000-nit display, a 35% larger 800mAh silicon-carbon battery with fast charging, EN13319 dive certification for the first time in a Galaxy Watch, a titanium case that is 1.4mm thinner, the new Snapdragon Wear Elite processor, and a set of advanced health features exclusive to the Ultra 2 that no other Samsung watch offers.
The 5,000-nit Super AMOLED display at 1.52 inches and 498×498 resolution is the brightest display Samsung has ever put in a Galaxy Watch — 67% brighter than the Watch 9's 3,000-nit panel. At 5,000 nits, the Ultra 2's display is clearly readable in direct sunlight, sand reflections, and the high-glare outdoor environments that UAE sports and adventure users encounter. The 1.52-inch size and 498×498 resolution make the Ultra 2's display the largest and most detailed in the Galaxy Watch lineup.
The 800mAh silicon-carbon battery is the Galaxy Watch's biggest-ever battery and its most significant practical upgrade. Silicon-carbon battery chemistry offers higher energy density than standard lithium-ion at the same physical size — the technology that makes the 800mAh cell fit in a watch body that is actually thinner (10.7mm) than the original Ultra (12.1mm). Fast charging reaches approximately 40% in 30 minutes using the EP-OL715 wireless charger — the first Galaxy Watch to support fast charging. Combined with the more efficient Snapdragon Wear Elite processor, the Ultra 2 delivers meaningfully longer real-world battery life than the original Ultra, which most users found lasted one day. Expect two full days from the Ultra 2 under regular use with features enabled.
EN13319 dive certification is the Galaxy Watch Ultra 2's most adventure-defining specification — the international standard for recreational diving equipment, certifying the watch as a diving computer. Using the Mares Dive app (available later in 2026), the Ultra 2 automatically tracks depth, dive time, water temperature, ascent/descent rate, and safe dive limits during recreational diving — features that previously required a dedicated dive computer. IP69K adds high-pressure water jet resistance (the industrial standard that withstands cleaning equipment pressure), alongside IP68 submersion and 10ATM water resistance. MIL-STD-810H military-grade durability certification. Titanium case. Sapphire crystal.
The Ultra 2-exclusive advanced health features are what separate it from the Watch 9 beyond durability and battery. Advanced Glycation End Products (AGEs) monitoring — the first time this feature has appeared in any Samsung smartwatch — uses optical sensing to estimate skin AGE accumulation, a biomarker associated with metabolic health and biological ageing. The Antioxidant Index tracks oxidative stress levels in the body. Blood Pressure Trend monitors directional blood pressure changes over time. These three features are not available on the Galaxy Watch 9.
Trail Run with Climb Guidance provides professional-grade trail running tracking: elevation gain, descent, average gradient, terrain impact, route direction, and real-time hydration guidance through Nutrition Alert — the features that let trail runners pace themselves, avoid injuries, and manage performance across variable terrain. Direct cycling sensor pairing — power meters, speed sensors, and cadence sensors — connects to external cycling hardware directly without a phone intermediary, and calculates FTP (Functional Threshold Power) from a connected power meter on the wrist. This capability is Ultra 2-exclusive across the Galaxy Watch lineup.
