Health monitoring

Listen to your body.

Getting to know your health status in depth is as simple as wearing a watch. Thanks to features like Sleep Quality, Cycle Tracking, and Vitals, the Apple Watch SE 3 gives you a global perspective on your well-being, every day and every night.

• Know your sleep quality. A good rest depends on many factors, such as the time you spend sleeping, the time you go to bed, the number of times you wake up, and the duration of each sleep stage. The Sleep Quality feature classifies all this data and scores it so you can see how your rest works and how to make nights more restful.
• Understand your cycle. The menstrual cycle is a fundamental indicator of your health. The Cycle Tracking app allows you to log your period and note symptoms. This way, you will have a clearer view of its patterns. It also notifies you if it detects any irregularities.
• Track your daily health with the Vitals app. With a single glance at the watch, you will know how your body behaved during the night. The SE 3 shows your heart and respiratory rate, wrist temperature, and the time you have spent sleeping. And it warns you if any of the variables fall outside of the usual values.
• Check your pulse with the Heart Rate app. Check your heart rate at any time and receive notifications if it gets too high or too low.

Fitness

Jump. Sweat. Keep going.

Surpass yourself step by step. From running to cycling, playing tennis, or practicing Tai Chi, the Apple Watch SE 3 offers endless ways to monitor your workouts. With in-depth insight into your physical progress, personalized encouragement, and real-time metrics, your goals are within reach.

• Close your Activity rings. Challenge yourself to meet your Move, Exercise, and Stand goals every day. Win awards, share results with your friends, and compete in a healthy way. You can pause or adjust the rings whenever you want, because resting is also part of the workout.
• The Workout app shows its muscle. Set a time, distance, or calorie goal and let the Apple Watch show your progress and a summary of the results. Access the features you use most directly, such as media playback, Workout Views, Pacer, and Custom Workout. When you finish, check how hard you worked in the Fitness app on your iPhone.
• Workout Buddy is in better shape than ever. Beat your personal bests with new data on pace, distance, and workout duration. Workout Buddy, now available in Spanish, knows your training history and gives you that extra push of motivation you need. You can finally leave your iPhone at home, because the Apple Watch's cellular data is more than enough.
• Move it. Crank it. Let the music lift the weights. Apple Music plays the perfect playlist for your workout because it knows your favorite songs. If you're in the mood, choose that list or podcast you love so much yourself.

So much to love

Look how easy it is.

• Always-On display. A glance is enough. A quick look at the screen during a meeting and that's it. Check your watch face, Live Activities, notifications, and apps like Workout if you have them open. And when you want to regain maximum brightness, just lift your wrist and let it shine.
• Smart Stack already thought of it. Smart Stack suggestions anticipate your needs to show you widgets just when you need them. Start a workout, wish your niece a happy birthday, find where you parked, or turn off the alarm on the weekend. It’s that simple.
• Long live the battery. Thanks to the efficiency of the S10 chip, you have 18 hours of battery life on the SE 3 to get the most out of its advanced features. And if the battery starts to fade, with fast charging you're back in action in no time.

Connectivity

Your world moves with you.

With the Apple Watch SE 3 on your wrist, everything is within reach. From connecting with friends and family or following the information you care about, to listening to your podcast. Wherever you go, your world goes with you.

• An active and connected life. The Apple Watch SE 3 has everything you need to stay in touch with what matters from anywhere. It is compatible with ultra-fast 5G networks so you can send messages, talk, download apps, and listen to music and podcasts when you are on the go.
• Use gestures. Tap your thumb and index finger together once to select a widget from the Smart Stack. Use double tap to answer calls, send messages, and much more, or turn your wrist to dismiss notifications and clear the watch face. Pure magic.
• Your watch is your wallet. Pay quickly with Apple Pay at any store where you see the contactless payment symbol. It's very convenient to use the Wallet app to always have your tickets or boarding passes handy. No more rummaging around.
• Hear where it is. If your iPhone decides to play hide-and-seek, tap the ping iPhone icon on the SE 3 to make it emit a beep that will guide you back to it. Sounds good.
• Don't get lost with Maps. Receive step-by-step directions with haptic feedback on the SE 3. The vibrations will indicate if you need to turn left, right, or if you have arrived at your destination. All without looking at the watch.
• Find it sooner with the unified Find My app. Locating people, devices, and items with the Find My app is easier than ever. Everything is shown on a map so you can see it instantly.
• Real-time Translation for your conversations. With Apple Intelligence on the iPhone, the Messages app translates text into your preferred language automatically. You'll understand it très bien.

Safety

Your safety is no accident.

The Apple Watch SE 3 comes packed with great new features to look after you. It is designed to call for help in an emergency, even if your iPhone is not within reach.

• Emergency SOS. In a flash. Do you need urgent help? Don't worry, because you have the Apple Watch SE 3. Press and hold the side button to attempt to call emergency services and share your location.
• Fall Detection comes to the rescue. The SE 3 detects if you have suffered a hard fall and can automatically call emergency services, send them your location, and notify the contacts you have set up for these cases.
• Crash Detection. Help is with you. If you have been in a severe car crash, the SE 3 can automatically call emergency services, share your location, and notify your designated contacts.
• Peace of mind reaches home. Your watch can notify whoever you want that you have arrived at your destination. When you go for a run at night, activate Check In during the way out and let them know when you are back.
• Backtrack. Go back the way you came. The Backtrack feature in the Compass app uses GPS to automatically show you the route you have followed, even when there is no signal. You can also add waypoints such as your starting point or a campsite.
• Set up your Medical ID. In an emergency, medical personnel can access important medical information such as whether you have allergies or take medication, all from the SE 3 screen.

Apple Watch for your Kids

Call Mom. Without a phone.

Your kids don't need a phone to wear an Apple Watch. You can set up any model with cellular connectivity from your iPhone. It is perfect for communicating, knowing where they are, and keeping them active in a fun way. Independence for them. Peace of mind for you.

• Your iPhone is in charge. Use your iPhone to pair as many watches as you want: any Apple Watch (GPS + Cellular) model will provide your child with their own Apple Account and phone number. You can set it up and manage it conveniently from the Apple Watch app on your iPhone.
• Communication is their thing. The watch allows children to communicate through calls and messages with people you approve. It is so easy they can do it just with their voice.
• Locate them with Find My. Check where everyone is with the Find My app and receive notifications when they have arrived at their destination. You can also set it up to receive alerts if someone leaves a location. For example, school. Nobody gets lost here.
• A tool to help avoid sensitive content. Communication Safety acts as a filter so that minors cannot send or receive nudity in Messages, video FaceTime, and other apps. And now it also intervenes before they see violent content in shared images and videos.
