Apple Watch Ultra introduces a 49mm titanium case and flat sapphire front crystal that reveals the biggest and brightest Apple Watch display yet. A customizable Action button offers instant access to a wide range of useful features. Apple Watch Ultra has the best battery life of any Apple Watch, reaching up to 36 hours during normal use.
Apple Watch Ultra provides the perfect balance of weight, durability, and corrosion resistance. The case rises up to surround all edges of the flat sapphire front crystal, protecting the Retina display, which is up to 2000 nits — 2x brighter than any Apple Watch display yet. The new Action button in high-contrast international orange is easily customized for instant access to a variety of features, including Workouts, Compass Waypoints, Backtrack, and more.
Apple Watch Ultra has three built-in microphones to significantly improve sound quality in voice calls during any conditions. An adaptive beamforming algorithm uses the microphones to capture voice while reducing ambient background sounds, resulting in remarkable clarity. In challenging windy environments, Apple Watch Ultra uses advanced wind noise-reduction algorithms, including machine learning, to deliver clear and intelligible audio for calls.
With the bigger, brighter display and rugged design, Apple Watch Ultra is the perfect technical tool for adventurers and explorers in a range of environments, from the every day to the extreme.
Backtrack uses GPS data to create a path showing where the user has been, which is useful if they get lost or disoriented and need help retracing their steps. It can also turn on automatically in the background when off the grid. With a single press of the Action button, users can quickly drop a Compass Waypoint or start or view a Backtrack.
Apple Watch Ultra includes all of the connectivity, activity, and health features that have made Apple Watch the best-selling smartwatch in the world — from heart rate monitoring and the ECG and Blood Oxygen apps, to Activity rings and Mindfulness, along with additional health, safety, and navigation features.
