The Apple Watch Ultra 3 is Apple’s most rugged and feature-rich watch yet, built for endurance athletes, divers, and adventurers.

A new highlight is two-way satellite messaging, enabling users to send and receive text messages when off-grid or outside cellular coverage. This complements the existing Emergency SOS functionality, making the watch a vital lifeline in remote environments.

The Ultra 3’s 42-hour battery is the longest in any Apple Watch, and Low Power Mode can extend runtime up to 72 hours. Outdoor athletes benefit from Waypoint and Night Mode watch faces, designed for navigation and visibility in challenging conditions.

For durability, the Ultra 3 uses a titanium case that is lighter yet tougher than stainless steel, and the display is the largest and brightest in Apple’s lineup with thinner bezels and a wide-angle OLED panel. Diving features are enhanced with Oceanic+ app updates, expanding safety metrics for recreational divers.

The Ultra 3 also inherits Series 11’s health capabilities, including hypertension alerts and Sleep Score, while maintaining rugged certifications for water resistance and durability.
