·I don't think this is an untouched dial.
If you look at 43 sec of small seconds, you can see that the ends of the circle don't fully meet each other.
Furthermore, if you look at the outer ring of the minutes track near the 7 hour position, you can see the same thing.
To me, this looks like a poorly refinished dial that has peeled off. The dial might have been painted with a cheap protective layer after the redial to fixate the paint on the dial. Cheap because it wasn't meant for this type of underground. And as a result you can see that a whole piece has fell off taking the markings with it.
I would try to put it back, maybe with a little bit of glue beneath the broken piece.
Back in the old day´s it was not uncommon with dials showing small imperfections, if you study samples there are imperfections in many Omega dials. (Example below.)
The dial is genuine in my opinion and the printing was done on the laquer. That´s why you can se this devastating result.
- With all do respect, it would be appreciated if opinions regarding redials and likevise were posted with some evidence or explanation. There are already a lots of people shouting "redial" out there.
An Omega from around 1940 - flaking with loss of print.
Irregular printing of markers...
