I saw an interesting YouTube video by UBreakiFixCo that compared sapphire vs Gorilla Glass although it was in terms of iPhone usage, not in a watch. It showed that sapphire was more scratch resistant and stronger than GG, but has less flexibility (bend) than GG. They said strength and flexibility both important in shatter resistance and concluded that sapphire and GG are both about the same in that regard. The video showed when GG hit its breaking point it would shatter into a million pieces, while when sapphire hit its breaking point it broke into only 10 big pieces. Anyway, for those you who have dropped a watch with sapphire on the ground outside, did anything break? I read that sapphire would likely chip, not break. Analog watches have a bezel to help protect the sapphire, but on the Apple Watch there's no bezel to help protect the display.
