Hi
I have seen about ten of these dials, first coming from a seller in Israel and then by others in Northern Europe. They are not original dials, Omega would never produce such poor quality dials. The word "chronometre" is spelled "chronometer", is in Helvetica font (totally wrong)
and it is in the wrong place, as it should be above the word Omega and below the symbol.
Also the line 12-6 does not intersect the symbol Omega right in the middle - something that a good quality control would not allow. The silver ring has not been satinised finely, the shine is very coarse.
I thing these are at the maximum some of the low-quality recent non-chronometer Omega reprints, which somebody has had added of the Chronometer word. The first ones that CR indicates in that posting that somebody linked to, a are of a much higher quality - and are only distnguishable from original because their subseconds dial is 6.5mm instead of the 8.5 mm of the original ones.
