Bezel
Piping Rock black enamel bezel

Losses at numeral edges and corners, with the remaining enamel flush and glassy. The expected state of a ninety-year-old worn example.
Re-enamelled or epoxy-filled bezel
AftermarketProbableWhole production
Uniform, slightly soft black that sits proud of the metal and does not chip. A legitimate restoration and a common one; it costs originality and must be recorded, but it says nothing against the watch.
