Samsung Galaxy Watch Ultra2 47mm LTE, 800mAh Battery, Titanium Gray

The Samsung Galaxy Watch Ultra2 is Samsung's most advanced and rugged smartwatch, built for adventurers who push into trail runs, open water, and off-grid terrain. This listing covers the 47mm LTE model in Titanium Gray, paired with a Black Marine Band in Medium/Large sizing (145mm to 205mm wrist circumference), and compatible with Verizon, AT&T, and T-Mobile LTE networks for independent cellular connectivity when your phone isn't nearby. A 1.52-inch (38.5mm) display reaches up to 5,000 nits of peak brightness, the brightest ever on a Galaxy Watch and well above the 3,000 nits on the previous Galaxy Watch Ultra, keeping stats like pace, route, and heart rate clearly visible even in direct midday sunlight. Powering the experience is the Snapdragon Wear Elite Platform, delivering faster app launches and smoother, more instant responses than earlier Galaxy Watch generations. An 800 mAh battery, the largest ever in a Galaxy Watch, supports up to 60 hours of use with Always On Display enabled, and Fast Charging, a first for the Galaxy Watch line, restores 40% of battery in about 30 minutes. Durability is backed by multiple certifications: IP69K rates the titanium body against dust and high-pressure, high-temperature water jets, 10 ATM confirms resistance to deep water immersion, MIL-STD-810H certifies resilience against extreme temperatures, shock, vibration, and humidity, and EN13319 certification qualifies the watch as a diving instrument for recreational scuba diving down to 40 meters. A dedicated Depth app surfaces real-time dive metrics, including current depth, water temperature, and elapsed dive time, for underwater activities down to 130 feet, while an Air Pocket design on the inner surface of the Marine Band lets sweat dry and water drain naturally during hard trail runs or open-water swims. Connectivity includes LTE, Bluetooth, dual-band Wi-Fi (2.4GHz and 5GHz), NFC for contactless payments, and dual-frequency GPS (L1+L5) for precise position tracking; Trail Run features let you load a GPX route and follow it turn by turn with real-time GPS guidance and Climb Guidance for gradient and elevation information ahead of each segment. Three distinctly spaced buttons, including a highly visible orange Quick Button, make custom actions easy to trigger even while wearing gloves; pressing and holding the Quick Button for 5 seconds activates an 86-decibel safety siren audible up to 180 meters away for emergencies outdoors. Health tracking runs through Samsung's BioActive sensor and includes FDA-cleared sleep apnea risk detection that monitors blood oxygen levels overnight, an ECG Monitor App for irregular heart rhythm notifications, Blood Pressure Trend estimates (calibration with a compatible blood pressure cuff required), fall detection with emergency contact notification, and a daily Heart Health Score based on sleep duration, blood pressure trend, BMI, and vigorous activity levels. Built for Android phones running Samsung Health, the Galaxy Watch Ultra2 pairs the durability of a rugged outdoor watch with the health insight and connected convenience expected from a premium Galaxy device.
