Powered by the S11 chip, Apple Watch Ultra 4 also features Apple’s redesigned Health Sensing System, more frequent heart rate and HRV measurements, and a personal Readiness score based on recent activity, vitals, and sleep. It brings together advanced fitness tracking, health insights, connectivity, and safety features in a watch designed to go farther. 

A rugged titanium design made for adventure

Apple Watch Ultra 4 comes in a 49mm aerospace-grade titanium case and is available in natural and black titanium finishes. Its display is made from sapphire crystal, while the watch has been tested to MIL-STD-810H standards for a range of extreme environments.

Ultra 4 is also rated IP6X for dust resistance and WR100 for water resistance. Apple says it is suitable for high-speed water sports and recreational scuba diving to depths of 40 metres. 

Train with precision GPS and advanced workout features

Apple Watch Ultra 4 is built with runners and endurance athletes in mind. Precision dual-frequency GPS supports accurate outdoor tracking, while workout features let you monitor metrics such as running power, cadence, Heart Rate Zones, pace, and training load.

You can create Custom Workouts, use Pacer to work toward time and distance goals, compare your performance with Race Route, and use Automatic Track Detection on supported tracks. The customizable Action button also gives you quick physical control over functions such as starting a workout, marking a segment, advancing to the next interval, or turning on the flashlight. 

Explore farther with hiking and navigation tools

For hiking and outdoor exploration, Apple Watch Ultra 4 includes tools designed to help you stay on course. The Hiking workout can track pace, distance, elevation gain, and calories burned, while Backtrack uses GPS data to automatically create a path showing where you’ve been when you’re off grid.

You can also create waypoints, build custom walking and hiking routes with turn-by-turn directions, and download offline maps on your iPhone that automatically sync to your watch. 

Understand your health and recovery

The redesigned Health Sensing System works with the S11 chip to provide higher-frequency heart rate monitoring. Apple Watch Ultra 4 can take background heart rate readings every five seconds and measure heart rate variability, or HRV, as often as every five minutes.

The Readiness experience analyzes your recent activity, vitals, and sleep to provide a daily score that can help you understand your capacity for activity and recovery. Ultra 4 also supports features such as sleep score, the ECG app, the Blood Oxygen app, Cycle Tracking, and heart health notifications. Feature availability and eligibility can vary. 

Battery life built for longer adventures

Apple Watch Ultra 4 offers up to 50 hours of normal use and up to 84 hours in Low Power Mode, giving you more flexibility for extended days, travel, training, and outdoor activities.

During workouts, Ultra 4 offers up to 18 hours of standard workout tracking and up to 45 hours with Max Extended Workout tracking. It also supports fast charging, with 15 minutes of charging providing up to 18 hours of normal use. 

Stay connected when you go off the grid

Built-in satellite communications help Apple Watch Ultra 4 stay connected when cellular service and Wi-Fi are unavailable. Emergency SOS via satellite can connect you with emergency services, while Messages via satellite lets you stay in touch. You can also use Find My to share your location by satellite with selected friends and family. 

When cellular coverage is available, Ultra 4 also supports 5G. With compatible service, you can text, make calls, download apps, stream music or podcasts, and use connected features without keeping your iPhone nearby. 

Safety features designed for the outdoors

Apple Watch Ultra 4 includes safety features such as Fall Detection and Crash Detection, which can help contact emergency services and share your location in supported situations.

Ultra 4 also includes an emergency siren that can be heard from up to 180 metres away. Hold down the Action button to activate it if you need to attract attention when you’re lost or injured. 

Ready for swimming, water sports, and diving

With its WR100 water-resistance rating, Apple Watch Ultra 4 is designed for more than everyday exposure to water. Apple says it is suitable for high-speed water sports and recreational scuba diving to 40 metres.

Compatible apps such as Oceanic+ can also turn Ultra 4 into a full dive computer that calculates and monitors dive information. 

A bright display with quick physical controls

The wide-angle Always-On Retina display reaches up to 3000 nits, providing a large, bright surface for workout information, maps, notifications, and everyday data.

The customizable Action button gives you quick physical access to frequently used functions. Depending on how you configure it, one press can start a workout, mark a segment, advance an interval, or activate the flashlight.
