Introducing Crash Detection. Help on automatic.

For the first time, Apple Watch Series 8 is able to detect if you’re in a severe car crash. When a crash is detected, Crash Detection can automatically connect you with emergency services, provide dispatchers with your location, and notify your emergency contacts.³ Crash Detection uses the combined power of an improved 3-axis gyroscope and a new g-force accelerometer that has the highest dynamic range in any smartwatch. It also uses a barometer, GPS, and an advanced sensor-fusion algorithm trained on over 1 million hours of real-world driving and crash data to detect if you're in a severe crash.

Always-On Retina display. Take it all in. Get it all done.

The bright Always‑On screen makes detailed watch faces look stunning and easy to read, even when your wrist is down. The large display accommodates all your favorite complications and makes tapping, typing, and swiping a snap.

Tougher than tough.

The same innovations used to create the beautiful, edge‑to‑edge Always‑On display also help make it incredibly durable. A thick front crystal, robust geometry, and flat base make it resistant to cracking.

Here’s to a healthier you.


The more informed you are about your health, the more empowered you are to affect it. Advanced health sensors in Apple Watch Series 8 provide insights to help you better understand your health.

Introducing temperature sensing.

Understand your cycle like never before. Apple Watch Series 8 has an innovative new sensor that tracks your temperature while you sleep, so you can see changes over time. Cycle Tracking uses this data to provide a retrospective estimate of when you likely ovulated, which can be helpful for family planning. When combined with your heart rate and logged cycle data, you’ll get a detailed view of your menstrual cycle.

Dream machine.

The Sleep app doesn’t just keep track of your time asleep. It shows you how much time you spent in REM, Core, or Deep sleep, as well as when you might have woken up.

Measure your blood oxygen. It’s a breathtaking innovation.

The remarkable sensor and app in Apple Watch Series 8 allow you to take on‑demand readings of your blood oxygen as well as background readings, day and night.

Makes taking your meds and vitamins like clockwork.

The Medications app helps you discreetly and conveniently keep track of your medications, vitamins, and supplements. And lets you easily log them from Apple Watch.

New ways to train. For your personal best.

Squat, spin, stride, you name it — Apple Watch has you covered in the enhanced Workout app. And with new Workout Views, you’ll be able to see more advanced metrics at a glance like Heart Rate Zones and customized intervals to keep you going strong.

Heart Rate Zones.

Quickly get a sense of your intensity level. Training zones are automatically calculated and personalized using your health data, or you can create them manually.

Race Route. Repeat it and beat it.

If it’s an Outdoor Run or Outdoor Cycle workout you do often, you can choose to race against your last or best result and receive in-the-moment updates to help you get there.
