iFixit says the new display uses “on-cell touch technology, similar to what Apple introduced in the iPhone 13.” The company said, “that’s a bit of a reversal—ordinarily the watch gets new display tech first as it’s a much lower-volume product.”
The physical diagnostics port has been removed from Apple Watch Series 7.
As for the Series 7 repairability score? The watch earned a 6/10, noting screen and battery replacements are still possible with Apple Watch Series 7.
