Background info: I own an Stainless Steel S2 42mm AW. My current situation: I love the look and feel of my SS AW; very durable. I wouldn't be upgrading right now, but an unfortunate incident regarding handling requires me to. I am looking at the Space Gray SS S4. I love how it looks. My current issue is that my current S2 has several micro scratches that are noticeable only under certain light conditions and/or if you go actually looking for them. I want a SS Space Black, but I already know how a Silver SS behaves. Just wondering how the Space Black look and feel holds up to those micro scratches that can occur during day-to-day usage. How visible are the scratches or dings that can happen? Any feedback from current S4 or S3 owners of SS Space Gray is appreciated. As a side note, not sure on whether to get 44 or 40mm. As I am a current 42mm, going either way isn't a big jump.
