Your comment reminds me of apple's attempt to make sapphire screens. That didn't turn out so well.

In short, I my watch has NOT had an easy life. I've made no attempt to protect it or taken it off for anything except charging. There is barely a mark on the screen. A sapphire screen will be a hard requirement for my next watch.
This is my second sapphire Garmin, and it's absolutely worth the premium.
Ever consider carrying a protein bar or two?
