I understand your concerns, I should have mentioned that the buyers does say that the bakelite insert is aftermarket. The lume on the 5 minute markes may or may not have been redone, but that is not the point. The point is that the dot at 6 oclock clearly has not been touched and is original, and the date on the certificate. Would be interesting to find the date on the guarantee.
For me personally the exclamation mark has been blown out of all proportion and does not merit the importance that some have given it.
