How is the Apple Watch 11 better than 10?
The key difference between the Series 11 and Series 10 screens lies in the glass covering. On the Series 11 aluminum models, Apple uses Ion-X glass, which it claims is twice as scratch-resistant as the glass on previous aluminum versions. The titanium Series 11 uses a sapphire crystal display. The key change this year, confirmed in our testing, is durability. The aluminum models of the Series 11 (the titanium models retain the same sapphire crystal glass as the Series 10) feature a new Ion-X glass that Apple claims is 2x more scratch-resistant.
