Apple Watch Ultra 3 is built for adventurers who push past where a standard smartwatch stops being useful. A rugged titanium case, the brightest display Apple has put on a watch, and genuinely long battery life come together in a device engineered for mountain trails, open water, and everything in between.

What Makes Ultra 3 Different

• A 49mm titanium case is corrosion-resistant, lightweight, and built to withstand extreme outdoor conditions without adding unnecessary bulk
• The Always-On Retina display reaches up to 3,000 nits of brightness, staying readable in direct sunlight where standard smartwatch screens wash out
• Dual-frequency GPS, combining L1 and L5 signals, delivers noticeably more accurate tracking in challenging environments like dense forests or dense urban streets
• A customizable Action button gives instant, physical access to functions like starting a workout or triggering the flashlight, no screen tapping required
• Built-in satellite communications let you text emergency services even without cell service or Wi-Fi nearby
• Water resistance to 100m covers swimming, snorkeling, scuba diving, and high-speed water sports
• Hard fall and severe car crash detection add an extra layer of safety during solo outdoor activity
• Health monitoring includes hypertension notifications, irregular heart rhythm alerts, sleep apnea notifications, and a full electrical and optical heart sensor suite
