Bulova 23 Self Winding Dial is Yellowed Slightly
I have a 1955 model Bulova 23. I noticed that the dial is a bit yellow near the crown side ot the dial. Not bad, but noticeable. Is there any way that I can clean this or should I leave it alone? I have ruined dials before, particularly clock dials becasue for the most part they are uncleanalbe. Not sure about this watch.
