One of my watches (not my VC) was the victim of a small cooking accident. The recipe called for lime juice, and some of it splashed on the sapphire glass without me noticing. I didn't realize the drop of lime juice until the morning after when I carefully cleansed it. It seems the acid ate away part of the coating.... it's barely noticeable, you'd have to really look at a certain angle in order to see it. Is it the type of thing that can be fixed or I eventually will need a new glass?
By the way, the culprit recipe was this one...
Thanks in advance for your advice.
