Health - Stay one beat ahead
Get meaningful insights about your health, just by wearing your Apple Watch SE 3. A new wrist temperature sensor enables deeper insights in the Vitals app and retrospective ovulation estimates in the Cycle Tracking app. You’ll also receive a daily sleep score and possible sleep apnoea notifications. It’s never been easier to live in the know.
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.8

Get retrospective ovulation estimates. SE 3 has advanced sensors that can track your wrist temperature while you sleep.1 The Cycle Tracking app uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning.

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.

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.

So much to love - A wristful of wonderful
The S10 chip — the same epic chip that runs Apple Watch Series 11 and Ultra 3 — comes to SE 3, giving you all‑new superpowers. Now the Always‑On display shows the information you want at a glance, without raising your wrist. And intuitive gestures, like double tap and wrist flick, make your watch even easier to control with just one hand when you’re holding a coffee or carrying shopping.
Just ask Siri. Now your favourite — and most private — digital assistant lives on your device and can handle helpful tasks without Wi‑Fi or cellular.
Get to it with gestures. Wrist flick lets you perform an action, like dismissing a notification, just by quickly turning your wrist over and back. And with double tap, you can answer a call, respond to a message, scroll through your Smart Stack and more. Abracadabra.

Make phone calls, minus the phone. With Apple Watch SE 3, you don’t need your phone handy to take or make a call — all you have to do is talk to the wrist. And with a mobile plan, you can leave your phone behind without missing a beat.15
Your watch is your wallet. Pay hands-free in an instant with Apple Pay anywhere you see the contactless symbol.16 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 SE 3 to play an audible chirp on your iPhone so you can locate it again. Sounds good.
Let Maps lead the way. Get turn-by-turn navigation on your SE 3 with haptic feedback. Left, right or arrived — you’ll know exactly where you’re going, without looking at your watch.
Easy listening. SE 3 connects seamlessly to your AirPods so you can listen to music, audiobooks or podcasts hands-free.6 And if you don’t have your AirPods nearby, you can now play media through the watch speaker.
Take a Smart Stack hint. The Smart Stack offers hints based on what’s immediately useful to you, like your daily workout. Now you can start leg day quicker than you can say “no pain, no gain”.
