I was interesting in obtaining an older piece, the LE electric blue. I wanted to know how the bezel is constructed and finished. I have been unable to read anything from UN. I thought that this piece had a guilloche base and enamel finish, with the arabic numerals being applied on top. I asking because I ran across a nice condition used piece and three of the zeroes on the bezel had an internal finish in white versus the electric blue, which I thought was a manufacturing defect. Do all of the UN bezels start as white enamel and then just painted for the various versions? Your inputs are appreciated.
