Apple Watch Series 8 offers all the great features you love, like an expansive, edge-to-edge display, great durability, fast charging, and industry-leading health capabilities. And it has two new sensors for even more heath and safety features. A temperature sensor enables advanced insights for cycle tracking, and a high-g accelerometer works with an improved gyroscope to detect severe car crashes and get help if you need it. Apple Watch Series 8 also offers advanced workout features, international roaming, a Low Power Mode that extends battery life, and a powerful, redesigned Compass app.

Design

• Edge-to-edge display with narrow borders has almost 20 percent more screen area than Apple Watch SE.
• Bright Always-On Retina display so the screen is easy to read.

Performance

• Swimproof with a water resistance 50 meter rating
• Enjoy all-day, 18-hour battery life.
• Get up to 36 hours of battery life with your iPhone present using Low Power Mode, which maintains core features while selectively disabling others.

Crash Detection

• High-g accelerometer and improved gyroscope work with the barometer, microphone, and GPS to detect severe car crashes, like front-impact, side-impact, rear-end collisions, and rollovers.
• If a crash is detected, Apple Watch sends you a notification—and if you don’t respond, it automatically calls emergency services, gives them your location, and notifies your emergency contacts.
