Apple Watch SE 3 GPS,

A new Always‑On display lets you read the time and more without raising your wrist.

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 apnea 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.9

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 analyzes 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.

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, it’ll motivate you to hit your goals like never before.

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 groceries.

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.

Great battery life.

On top of all these new features, the power‑efficient S10 chip allows SE 3 to deliver all‑day, 18‑hour battery life.2 And with new fast charging, you can charge up in a flash.3
