I already have the graphite SS, I mentioned I was considering returning it for a titanium since I’ll be keeping the watch for 2 years, would be nice for it to stay pristine since it’s now been confirmed that the graphite SS does not have a DLC coating (like the SBTi) but rather a PVD coating.
Your graphite SS should hold up really good with PVD. My gold SS S4 has PVD & it looks amazing after 3 years of daily use.
