My immediate reaction is that the dial has been re-painted.
The markings are wonky/irregular and ill defined.
The Omega text is blobby and I can see no Swiss Made.
The sub-dial still has a nice clean pattern and the Pontife hands are quite nice.
While we expect perfection these days, at the time this dial was made, printing equipment and techniques were not as sophisticated as they are now, even though, I still think it's re done.
I hadn’t appreciated that you didn’t own the watch.
Although photos, particularly through crystals, can distort if you look at your photos, the minute markers appear to vary and lack the consistency that you might have expected.
