Apple Watch Ultra 4 GPS 49mm Black Trail Loop strap

Apple Watch Ultra 4

The Apple Watch Ultra 4 comes with satellite communications to keep you connected and safe even when you're off the grid.

A long-distance runner.

The Apple Watch Ultra was designed to be the ultimate running watch, with advanced features to train smarter and high-precision dual-frequency GPS. The Ultra 4 raises that bar, arriving packed with revolutionary health and fitness features that will boost your performance. Plus, it gives you plenty of battery life to reach your goals. No matter how far away they are.

Innovation beats strong.

Knowing how your heart is doing is key to understanding your performance and your overall well-being. The S11 chip is integrated into a completely redesigned measurement system, with more powerful optical and electrical sensors to record your heart rate at shorter intervals. Together with larger, more efficient green LED indicators, it is able to offer you even more relevant data about your health.

Vitals. This new feature shows you with a single number how your body is doing for the day ahead. The score is calculated each morning based on an analysis of your recent physical activity, vital signs, and sleep, and it adjusts as the day progresses. Whether you’re training for a marathon or running around to get everything done, you can dedicate your energy to what really matters.

HRV is under control. Heart Rate Variability (HRV) indicates how your body responds to strain and recovery. Overtraining or poor sleep can increase stress and, consequently, reduce HRV. Thanks to the most precise heart rate measurement in a wearable, the Apple Watch Ultra 4 monitors HRV every five minutes and records your heart rate every five seconds—more often than any other Apple Watch. Additionally, the updated Heart Rate app introduces complications so you can always have your data at hand on your watch face.

Your data works in your favor.

The Ultra 4 goes a step further and offers you very precise information about your sessions. With real-time metrics, comprehensive data on your workouts and performance, and a good dose of personalized motivation, there will be no goal you can't conquer.

Extreme resistance.

Optimized and super-efficient training algorithms allow the Ultra 4 to offer you even greater battery life. It doesn't just last up to 50 hours of normal use; it now goes up to 18 hours of standard workouts. And if you’re pushing to the limit, it reaches up to 45 hours in Maximum Extended Workout mode. That’s enough for an ultramarathon.

Boost your performance with a great team of metrics.

Data is a very powerful ally when it comes to optimizing your performance. With advanced health monitoring features, the Apple Watch Ultra 4 gives you an even more complete view of your health.

Ultra-versatile.

The Apple Watch Ultra 4 excels in any sport. When cycling, it keeps track of your speed and performance to show you your progress in real time. And in the water, it recognizes your swimming style, logs your sets, and calculates your total distance. Victory starts on your wrist.

Equipped to go the distance.

Conquering peaks and exploring the depths of the ocean requires specialized gear. That’s why the Apple Watch Ultra 4 focuses on revolutionary features, such as an advanced compass and a full dive computer. Light gear for such a long journey.

Connect with safety.

When you run out of Wi-Fi or data, the Apple Watch Ultra 4 gives you a hand with integrated satellite communications. If things get tough, you know you can contact emergency services. Plus, it’s loaded with new features to look after you and is designed to call for help when you need it most, even when your iPhone isn't within reach.
