This is what happens when you drop your Apple Watch from 3-4 feet high onto concrete.
The tester here got pretty agitated when he saw the cover glass broken. Apparently he was not prepared to see the damage done by his test.
Good to know anyways: the sport edition does not include sapphire glass. That is only reserved for the pricier versions.
My recommendation: Don’t try this at home!
