So I have the SS Series 0 and Nike Sport Series 3.. Obviously SS Series 0 had sapphire glass and I've treated it terrible yet the glass is immaculate. My girlfriend has also been wearing it since I had my AW3 The Nike Sport Series 3 is the same story. Today... I caught my SS AW4 on a stainless steel hand rail and it scratched instantly! Surely this shouldn't scratch so easy!?
