Apple Watch Ultra 4, 49mm, Black Titanium Case, Black Titanium Milanese Loop, Medium, (GPS+Cellular)

Advanced Health and Fitness Tracking.

Apple Watch Ultra was designed to be the ultimate running watch, with powerful features that help you train smarter and precision dual-frequency GPS. Now Apple Watch Ultra 4 takes it to the next level with game-changing health and fitness tracking to help you elevate your performance. And new extended battery life for workouts to keep you moving toward your goals. Run better, run longer.

Heartcore innovation.

Heart data is fundamental in tracking your overall health and performance. Redesigned with more capable optical and electrical sensors, the all‑new Health Sensing System works with the S11 chip to provide higher-frequency heart monitoring. The updated sensors and larger, more power-efficient green LEDs give you richer heart data for more meaningful insights.

Ready advice.

The new readiness experience can help you determine your capacity to take on the day by providing you with one simple score. Your score is determined each morning by analyzing your recent activity, vitals, and sleep — and it adjusts as you go about your day. So whether you’re training for a race or juggling a busy schedule, you can spend your energy on what matters most.

HRV? Check.

Heart rate variability, or HRV, is an indicator of how your body responds to stress and recovery. Overtraining or poor sleep can raise your stress and lower your HRV. With the most accurate heart rate sensing in a wearable, Apple Watch Ultra 4 measures HRV as often as every five minutes and takes background heart rate readings every five seconds — the most frequent sensing ever for Apple Watch.

Run circles around your data.

Ultra 4 goes the extra mile to ensure that you can precisely track and analyze your running workouts. With real‑time metrics, deeper insights into training and performance, and personalized encouragement, you’ll be motivated to hit your goals like never before.

Push your progress with enhanced Workout Buddy.

Get real-time encouragement right when you need it with new insights about your pace, distance, and workout progress.

Boost your performance with a body of metrics.

The more health insights you have, the more empowered you are to take actions that will optimize how you perform. With in-depth clinical validation and FDA-cleared features, Apple Watch Ultra 4 provides a fuller picture of your health, so you can stay informed.

Heart this app.

Check your heart rate at any time with the Heart Rate app. And get notifications of a high or low heart rate or an irregular rhythm.

Wearable AI Assistant

Say hello to Siri AI.

With all-new Siri AI, Apple Watch Ultra 4 can tap into broad world knowledge and your personal context to be even more helpful. Using just your voice, you can engage in natural, back-and-forth conversations, brainstorm ideas for workout routines, and get the latest wellness tips with Siri — all from your wrist. And now Audio Intelligence uses the built-in microphone and secure S11 chip in Ultra 4, alongside the power of Apple Intelligence, to make sense of what you hear in a private and secure way. Just as Visual Intelligence on iPhone helps you make sense of what you see.

More Sports

Ultraversatile.

Apple Watch Ultra 4 ups your game in every sport. When you’re cycling, it actively monitors your speed and efficiency so you can see your progress in real time. And in the water, it can track your sets as you swim, automatically detect stroke patterns, and calculate your total distance. Time to clock your best.

Adventure

Geared to go farther.

Hiking to new heights and diving to new depths requires specialized tools. Apple Watch Ultra 4 has pioneering features like a powerful compass and a full dive computer, so you can pack light and still be equipped for every expedition.

Blaze a trail with custom routes.

Create and save custom walking and hiking routes on your iPhone. Choose from different route options

Plan ahead and download a map of where you’ll be hiking on your iPhone. It will automatically sync to your watch.

On the Go

Connected. Protected.

Now when you’re off the grid without cellular or Wi-Fi, Ultra 4 can help you stay connected using built-in satellite communications. So wherever adventure takes you, you can still keep in touch with loved ones. And if you need critical help, you can contact emergency services via satellite — right from your wrist. Packed with innovative safety firsts, Apple Watch Ultra 4 has your back. It’s designed to summon help when you need it most — even if you can’t reach your iPhone.
