Sub durability

[j.mo]

I have a question about the durability of my sub.
I ordered an 116610 from thanh a few months ago in April. It's been a daily wearer for me, to work, out, wherever.
I try and avoid any contact with it to avoid as many scratches and blemishes as possible. But I'm noticing a few. I thought this 904 stainless was virtually indestructible? So is this thing the real deal or what. Because I know the replicas use a softer inferior stainless. I've not yet had it authenticated because I've taken the good word of the many trusted members here.
So can someone help me out and explain the expectations?
