Apple Watch Series 8 features a big, brilliant Always‑On display. Narrow borders push the screen right to the edge, resulting in an elegant integration with the curvature of the case.

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.

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.
