Curious if anyone ever seen a dial in such bad condition yet the name, logo and minute track in good condition? Curious what could cause such a thing. Heat perhaps?
Seems like this one and I have no idea what happened but that is too much even for me (who likes patina)
Actually no, blue dials have unique and distinct way of deterioration. Regular silvered and lacquered dials its usually damage to the lacquer and then the underling finish.
