The display was completely re‑engineered reducing the borders by 40%, allowing for more screen area than both Series 6 and Series 3. The remarkable sensor and app in Apple Watch Series 7 allow you to take on‑demand readings of your blood oxygen as well as background readings, day and night. You don’t need to raise your wrist or touch the screen to see the time or other information and complications on your watch face, because the display is always on.

The entire charging system for Apple Watch Series 7 has been rethought to get you up and running faster than ever. With an updated charging architecture and fast-charging USB-C cable, it takes about 45 minutes to go from 0 to 80% charge.

The front crystal is over twice as thick at its tallest point as Apple Watch Series 6, adding strength and durability. The touch sensor has been integrated into the OLED panel, creating one unified component and reducing display thickness and borders.

With the ECG app, Apple Watch Series 7 is capable of generating an ECG similar to a single-lead electrocardiogram. Across the system, buttons have been redesigned to take advantage of the larger display. So using apps like Calculator, Stopwatch, and Timer is easier than ever.
