The Samsung Galaxy Watch Ultra 2 is the most powerful, most durable and most capable Galaxy Watch ever made — delivering the world's first 5,000-nit smartwatch display, Samsung's largest-ever watch battery at 800mAh with the first-ever fast charging on any Galaxy Watch, full EN13319 dive instrument certification to 40 metres, IP69K high-pressure water resistance and the Snapdragon® Wear Elite Platform in a slimmer, more refined titanium design than the first Galaxy Watch Ultra, with LTE 4G independence from your phone and the most comprehensive suite of outdoor athletic tracking features Samsung has ever built into a wearable. The 5,000-nit Super AMOLED display at 498 × 498 pixel resolution and 1.52 inches is the most significant display advance in smartwatch history — the first display bright enough to remain fully readable through direct overhead sunlight, on snow-reflected light, on water surfaces and even through shallow water during a dive, where light refraction and surface reflection defeat every conventional smartwatch display. At 5,000 nits, the Galaxy Watch Ultra 2's display is 67% brighter than the first Galaxy Watch Ultra's 3,000-nit panel and more than five times brighter than a typical consumer smartwatch — delivering pace, route, heart rate and every other training metric with absolute clarity at a glance under any outdoor lighting condition imaginable. The 498 × 498 pixel resolution on the larger 1.52-inch panel — up from 1.47 inches on the first Ultra — delivers the sharpest, most text-clear and most information-dense display on any round smartwatch, making even small health metrics and notification text readable without needing to look twice.

The 800mAh battery is the single most consequential upgrade the Galaxy Watch Ultra 2 delivers over the first-generation Galaxy Watch Ultra — a 35% larger cell that provides up to 80 hours of continuous use with Always-On Display disabled and up to 60 hours with AOD enabled, extending the watch's active life from the two-day typical endurance of the first Ultra to three-plus days for most users before recharging. The first-ever fast charging on any Galaxy Watch — charging the 800mAh cell to 40% in just 30 minutes from the dedicated wireless charger — addresses the only meaningful practical limitation of a large-battery smartwatch by ensuring that even a brief charge session from empty restores enough power for a full day's use, making the Ultra 2 genuinely practical for ultra-athletes, expedition users and anyone who cannot maintain a reliable daily charging routine. The EN13319 dive instrument certification is the feature that makes the Galaxy Watch Ultra 2 categorically different from every other smartwatch — an internationally recognised standard for diving instruments that certifies the watch for use as a functional dive instrument to 40 metres depth, providing real-time current depth, water temperature and elapsed dive time continuously through the dedicated Depth app during recreational diving and snorkelling. IP69K adds resistance against high-pressure, high-temperature water jets — the highest water resistance rating on any Galaxy Watch — alongside 10 ATM submersion rating and MIL-STD-810H military-grade certification against temperature extremes, shock, vibration, altitude, humidity and salt fog.

The Dual GPS system with both L1 and L5 frequency tracking provides significantly more accurate positioning than single-frequency L1-only GPS — with L5's wider bandwidth and higher power signal cutting through the atmospheric interference, building reflections and canopy obstructions that cause L1-only GPS to lose accuracy in forests, urban canyons and mountain valleys where outdoor athletic tracking is most commonly performed. Trail running gains a full dedicated feature set: GPX route import for turn-by-turn navigation with real-time GPS position tracking along pre-planned courses, Climb Guidance for checking average gradient and elevation gain ahead of each segment before the hill slows you down and Water Intake Alarm for hydration reminders timed to your actual pace and exertion level during long trail sessions. The 86-decibel Safety Siren activates from five seconds of the orange Quick Button press and carries up to 180 metres — providing genuine emergency signalling capability deep in the backcountry where phone signal is absent. The comprehensive health platform matches the Watch 9 in every dimension — Vitals overnight monitoring of heart rate, HRV, respiratory rate, skin temperature and blood oxygen; Sleep Coaching; FDA-approved sleep apnoea risk detection; Energy Score; Fitness Index; Running Coach; Daily Cardio Load; Heart Health Score and the new Vascular Load feature that tracks long-term cardiovascular health trends during sleep using PPG sensors. Google Gemini with Raise to Talk, WearOS 7, Bluetooth 6.0, Wi-Fi dual-band, NFC and LTE 4G with embedded SIM complete the most comprehensively specified smartwatch Samsung has ever made. Security updates guaranteed until 31 July 2031.
