The Apple Watch Series 7 is the most durable Apple Watch to date, with a stronger, more crack-resistant front crystal. It is the first Apple Watch to have an IP6X certification for resistance to dust, and maintains a WR50 water resistance rating. Featuring a larger and completely new Always-On Retina display with thinner borders. The narrower borders allow the display to maximize screen area, while minimally changing the dimensions of the watch itself. The design is still based on a rounded design language but now more refined with softer and more rounded corners. With the improvements to the display, users will benefit from the same all-day 18-hour battery life but now with 33 percent faster charging. Still offering indispensable tools for health and wellness, like electrical heart and Blood Oxygen sensors. With the WatchOS 8 the user interface is optimized for the larger display, offering greater readability and ease of use, plus two unique watch faces, Contour and Modular Duo, designed specifically for the Series 7. It will help users stay healthy, active, and connected through new workout types, the new Mindfulness app, innovative accessibility features, greater access with Apple Wallet, and more capabilities with the Home app, along with enhancements to Messages and the Photos app.
