I also think this is a redial, but would not claim to be an expert. I don’t have a macro picture of my C-case, but even this picture shows the difference in the fonts and letter spacing under the Omega applied lettering:
Basically the text one yours looks to be sans serif there.
If this is a redial (and this is often what dealers mean by “restored”), it means that a third party has repainted the dial in as close as they can get to the original Omega printing. Sometimes that’s very close and other times less so.
if you like the piece and it speaks to you, there’s nothing really wrong in owning and wearing a redialled watch, but its value to a collector will be a fraction of what you’d get if it was an untouched original. Chances are, no one you will ever meet will know the difference, and it will probably be more presentable as a smart dressy watch than an untouched (but well worn) original. But you would know it isn’t entirely original and that might start to eat away at you until you replace it with something that is!
