Is it disappointing that the Apple Watch is scratchable, given the grade of materials and manufacturing process Apple used? Sure. But Science: stainless steel is not a super-hard material. The 316L grade used in Apple Watch is actually softer than the 7000 series aluminum used in Apple Watch Sport. If you’re curious as to where 316L is positioned within grades of stainless steel, check out
this helpful chart. Apple could have chosen to go with more durable 904L stainless steel, but it’s much more expensive to manufacture and would raise Apple Watch’s price. With a polished finish, even 904L can still be scratched fairly easily. You won’t run into this issue with brushed stainless steel watches because that texture hides any accidental scuffs within the texture/finish.
