The numbers on this dial are filled with clear resin the same as the authentic dials (not a plexi). The anodized dial surface has also been aged. Different watches had different Indices (number) thickness. For example the non sub-dial MM Dial (Rolex movement) had slightly thicker numbers than the sub-dial MM Dial (Angelus Movement). This is because of the different ages of the dial. The early dials (1940’s) had quite thick numbers (note the 3646) and the later 1950’s dials had thinner numbers (6152 LP and MM). Both dial type number thickness do not have to be totally accurate, the thickness varied a little on all types.
