Apple Watch Series 4 is redesigned and re-engineered to help users stay connected, be more active and manage their health in powerful new ways. The fourth-generation Apple Watch has been refined, combining new hardware and software enhancements into a singular, unified form. The display is over 30 percent larger and seamlessly integrates into the thinner, smaller case, while the new interface provides more information with richer detail. The watch brings advanced features like revolutionary health capabilities such as fall detection and the ability to take an electrocardiogram using the new ECG app.
