Health sensors
Apple Watch SE 3 uses innovative sensors — including a heart sensor and wrist temperature sensing — to stay on the pulse of your health.
Motion sensors
A gyroscope, an accelerometer and GPS work together to track your activity, deliver accurate fitness metrics and enable safety features.
Durable Ion-X display
With the toughest glass in the industry, the display is 4x more resistant to cracks than Apple Watch SE 2 — perfect for everyday use.
Speaker and microphone
You can take and make phone calls, dictate messages and listen to music or podcasts out loud — right from your wrist.
Water resistance
Apple Watch SE 3 has a water resistance rating of 50 metres.8 So whether you’re splashing, swimming or surfing, it’s swim‑suitable.
Health Tracking - Let your body do the talking
Unlock deeper, more meaningful health insights that are uniquely yours just by wearing your Apple Watch. From sleep score to cycle tracking to daily vitals, Apple Watch SE 3 helps you understand your health, night after night, day after day.
Know your sleep score
Sleep quality is influenced by factors such as sleep duration, bedtime consistency, how often you wake up and time spent in each sleep stage. Sleep score analyses these factors every night and provides a classification and a score. You’ll see how the score is calculated, so you can understand the quality of your sleep and learn how to make it more restorative.
Get the inside track on your cycle
Cycle Tracking is with you through every stage of your menstrual health journey. Log your cycle and get predictions for your period, fertile window and retrospective ovulation estimates. And find support for perimenopause and menopause. Welcome to the new status flow.
Track your daily health status in the Vitals app
Quickly see your overnight health data right on your wrist — including heart rate, respiratory rate, wrist temperature and sleep duration — and get notified if your metrics are ever outside your typical range.
Spot signs of sleep apnoea
Sleep apnoea is a condition where people experience repeated interruptions in their regular respiratory pattern during sleep. If untreated, it can lead to increased risk of hypertension, type 2 diabetes, cardiac issues and more. SE 3 can monitor for breathing disturbances over time and notify you of possible sleep apnoea.
Get a pulse check with the Heart Rate app
Check your heart rate at any time with the Heart Rate app. And get notifications for a high or low heart rate or an irregular rhythm.
Fitness - Step. Sweat. Strive
Make every move count. From running to riding your bike, tennis to tai chi, Apple Watch SE 3 gives you a healthy number of ways to track your workouts. With real‑time metrics, deeper insights into your fitness progress and personalised encouragement, it will motivate you to hit your goals like never before.
Close your Activity rings
Track your daily Move, Exercise and Stand goals with Activity rings. Earn awards and share progress with your community for some friendly competition. And pause or adjust your Activity rings at any time in the Activity app.
A more powerful Workout app
Set goals for time, distance or calories, and let Apple Watch track your progress and summarise your results. Jump straight to your favourite features, like media, Workout Views, Pacer and Custom Workouts. Then head to the Fitness app on iPhone to see how far you’ve come.
Your Workout Buddy has levelled up
Smash your personal record with new data insights on your progress for pace, distance and workout duration. Enjoy personalised motivation based on your fitness history, now available in Spanish.13 And you can finally leave your iPhone at home — all you need is Apple Watch with cellular.
Move it. Groove it
Feel the burn with just the right beats. Let Apple Music pick the perfect playlist based on your workout and music preferences — or choose a playlist or podcast on your own.
So Much to Love - Easy does it
Got a question? Just ask Siri AI, your wearable AI assistant. It can dig up the door code you saved in Notes, your driving licence from Photos, or that Italian restaurant your friend mentioned in Messages. You can even get ideas for post‑workout stretches, healthy recipes or wellness tips. And Siri is just the beginning. Apple Watch SE 3, smart in more ways than one.
Revisit conversations in the Siri app
Ask Siri a question on your iPhone or any other Apple device synced with iCloud, and pick up where you left off on your Apple Watch. Pin conversations and see the same content, including images, across your devices. Here’s to a little more conversation and a lot more Siri.
All the info you want. Always-On display
Whether you’re in a meeting or mid‑conversation, a quick look is all it takes. See your watch face, Live Activities, notifications or active apps like Workout — all at a glance. And to bring your display to full brightness, simply raise your wrist. Let there be light.
The Smart Stack thinks of it before you do
Smart Stack suggestions are smarter than ever, surfacing timely widgets right when you need them. Start a workout, wish your bestie a happy birthday, find where you left your car, or adjust your morning alarm before a holiday.
Great battery life
On top of all these features, the power‑efficient S10 chip still allows Apple Watch SE 3 to deliver all‑day, 18‑hour battery life. And you can top up in a flash with fast charging.
- Up to 8 hours of normal use with a 15‑min fast charge
- Up to 32 hours of normal use with Low Power Mode
On the Go - Take your world with you
With Apple Watch SE 3, life on the go has never felt so connected.

Stay active and connected
With Apple Watch SE 3, you can keep in touch with the people and things that matter most, no matter where you are. Superfast 5G capability lets you text, talk, download apps and stream music or podcasts on the go.
Get to it with gestures
Just tap your index finger and thumb together once to select a Smart Stack widget. A double tap answers calls, sends texts and more, and a wrist flick dismisses notifications and returns to your watch face. It’s single‑handedly simple.
Your watch is your wallet
Pay hands‑free in an instant with Apple Pay anywhere you see the contactless symbol. You can also use the Wallet app with your ticket or boarding pass. Smart.
Ping my iPhone
Can’t find your iPhone? Just tap the Ping iPhone icon on your Apple Watch SE 3 to play an audible chirp on your iPhone so you can locate it again. Sounds good.

Crash Detection. Your guardian on the go
If you’ve been in a serious car crash, SE 3 can automatically help call emergency services, share your location and notify your emergency contacts.
When you’re out, Check In
Your watch can automatically notify someone when you arrive at your destination. And if you’re going for a run after dark, you can start a Check In for the duration of your workout to let a friend know when you’re done.
Let Backtrack get you back on track
Backtrack in the Compass app uses GPS data to automatically create a path of where you’ve been when you’re off the grid. Easily add waypoints for anything of interest, like the trailhead or your campsite.
