So I own a series zero and a series for SS silver currently. I really like the look of the new graphite SS version, but the scratching makes me nervous. I get scratches pretty often on my current watch, but the good thing about the raw SS is I can easily buffed them out. I have heard good things about the DLC coatings on the graphite and space black, but once a scratch there is no buffing those out. So now I am really torn on what to go with. How strong is this DLC coding for daily use?
