Bezel insert

The unidirectional diving bezel of the modern Seamaster and Planet Ocean, in polished ceramic with the scale recessed and filled with Omega's Liquidmetal or white enamel depending on execution. The scale is IN the ceramic rather than printed on it, which is the whole point for an examiner: a printed scale on a bezel that should be filled is visible under a loupe as ink sitting on a surface rather than material sitting in a groove, and it will show wear at the edges that a filled scale does not.
