The dial looks all original to me. I saw it on ebay, but didn't pay too much attention to it. My guess is the dial was made specifically for advertising for a dealer. A display type watch. Only thing that gets me is its in a wrong case (not chesterfield) fromt he looks of it. Very possible it was in a solid 14k chesterfield case which has since been scrapped? The porcelain dials were only put on very early grades of the 12s series from my observations.
