Thank you.
The Series 10 actually has a larger display (1220 sq mm) than the Ultra 2 (1185 sq mm).
The new Ultra 3 raises that to 1245 sq mm. The new Series 11 keeps the same size as the Series 10.

TBH I only use the Apple Watch as a dumb watch. I have disabled all notifications and smart features. Just time and heart-rate when I exercise.
