Bezel

Piping Rock black enamel bezel

Probable

The separate enamel bezel insert carrying the hour numerals. It is what makes the model and it is what fails: fired enamel chips at the numeral edges and case corners rather than wearing smooth, so a chipped bezel is age evidence and an immaculate one needs explaining.

  • Original fired enamel, chipped

    Whole production

    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

    AftermarketProbable

    Whole 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.
