The Galaxy Watch Ultra2 in Titanium Silver is Samsung's rugged cellular smartwatch for users who spend long days outdoors or on the job. This US model (SM-L715UZSAXAA, XAA unlocked US variant) comes with an Olive Marine Band in Medium/Large. The band has an Air Pocket inner surface that lets sweat dry and water drain. The watch connects over LTE through an embedded SIM and also supports Bluetooth 6.0, 2.4/5GHz Wi-Fi, NFC for contactless payments and dual-frequency GPS (L1+L5). LTE availability depends on your region and carrier.
The titanium body carries IP69K, 10 ATM, MIL-STD-810H and EN13319 certifications, and the watch tracks dives down to 40 meters. The 1.5-inch 498 x 498 Super AMOLED display reaches 5,000 nits, so it stays readable in direct sunlight. Its three widely spaced buttons work with gloves on. The 800 mAh battery is rated for up to 60 hours with Always On Display on and up to 80 hours with it off. The included Fast Wireless Charger adds 40% in about 30 minutes when used with a 5V/2A or higher PD adapter.
For safety, the watch detects hard falls and contacts help if you don't respond. Five presses of the home button call emergency services, and holding the Quick Button for five seconds sounds an 86-decibel siren that carries up to 180 meters. Outdoor tools include GPX turn-by-turn guidance, Track Back, Climb Guidance and water intake reminders. Health features include Energy Score, Vitals, sleep apnea detection, Blood Pressure Trend (calibration cuff sold separately) and Heart Health Score. Samsung lists security updates through 31 July 2031.
