The Apple Watch SE 3, 40 mm with GPS + Cellular, brings powerful health, fitness, and safety features in an elegant Moonlight aluminum finish. It offers advanced health sensors, durable Ion‑X glass, water resistance to 50 m, intuitive gesture controls, and all‑day battery life. With built‑in GPS, cellular connectivity, and calling right from your wrist, you can stay connected even without your iPhone.
Health under control
Track heart rate, breathing, and sleep trends with clear stats in the Health app. The wrist temperature sensor provides deeper insights (including ovulation estimates in the Cycle Tracking app), alerts for potential sleep apnea, and notifications for high or low heart rate and irregular rhythm.
Fitness and training
The Workout app delivers precise metrics from GPS, the accelerometer, and the gyroscope. Close your Activity rings, stay motivated with awards, and share your progress. The improved interface with quick controls and personalized audio cues from Workout Buddy help you hit your goals. Music from Apple Music keeps every workout in rhythm.
Performance, control, and endurance
The S10 chip ensures fast response and smooth performance. The Always‑On display lets you check information at a glance. Gesture controls (double tap, wrist “flick”) make it easy to answer calls, reply to messages, and work quickly with widgets. Up to 18 hours of battery life with fast charging gets you through the day.
- Safety: SOS, Fall Detection, and Crash Detection automatically call emergency services and share your location.
- Connectivity: GPS + Cellular for calls, messages, and data even without an iPhone (carrier plan availability may vary).
- Lifestyle: Apple Pay in Wallet, Find iPhone, turn‑by‑turn haptic directions in Maps, wireless pairing with AirPods.
