Apple Watch Series 8 41mm | 45mm

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.

Period predictions. Less of a question mark.

Get improved period predictions with wrist temperature data. And now you can receive notifications if your logged cycle data shows a possible cycle deviation, like irregular or prolonged periods. You can share your cycle history with your healthcare provider for more informed conversations.

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.

Take an ECG at any time.

With the ECG app, Apple Watch Series 8 is capable of generating an ECG similar to a single‑lead electrocardiogram.

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.

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.² 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 microphone, 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.

Fall Detection.

Apple Watch Series 8 can detect if you’ve taken a hard fall and connect you with emergency services if you’re immobile. And it’s optimized when you are using the Workout app.

Emergency SOS.

Press and hold the side button and Apple Watch can call local emergency services to share your location.
