Physics be damned. The challenge was to create a bigger display while barely expanding the dimensions of the watch itself. To do so, the display was completely re‑engineered, reducing the borders by 40%, which allows for nearly 20% more screen area than Series 6. And over 50% more screen area than Series 3. That’s something to smile about.
Always-On Retina display. A brighter view of you. 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. And now it’s 70% brighter indoors when your wrist is down.

The edge of design.
A subtle wraparound effect is created by refracted light at the edge of the display for a seamless integration with the case.

Apple Watch Series 7 Displaying Calculator App
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.

As ever, you still need to stay in the same smaller or bigger watch version to keep band compatibility.

What are the new Apple Watch sizes?

Apple Watch Series 7 comes in two new sizes: 41mm (smaller size) and 45mm (larger size). Here’s how band compatibility works with the new sizes:

• Smaller: 38mm, 40mm, 41mm
• Larger: 42mm, 44mm, 45mm

Apple Watch sizes refer to the vertical case height which has increased over the years, but the width has maintained a similar enough size to not break band compatibility yet.

Where are the space gray and silver colors?

Apple Watch Series 7 has refreshed case colors for all aluminum models:

• midnight (replaces space gray)
• starlight (replaces silver)
• green (first-time color)
• blue (lighter than last year)
• red (deeper color than last year)

It’s also important to note that Apple is emphasizing that faster charging is unlocked on Series 7 only when using the “fast-charging USB-C cable” that ships with the new Apple Watch.

Our understanding is that Series 7 will not see these faster charging times when powered by Apple’s MagSafe Duo charger or other multi-charging docks. Actual testing when Series 7 is available will be required to present firm numbers.
