Help with a 1956 cal 491 piece

Hi,

I found this piece and I'm really interested in acquiring it but I have some doubts about it. It shows very well but unsure about this combination of dial, case and movement. From the photos you can tell it's a caliber 491 with serial number in the 15,000,000 which places this piece around 1956+. Haven't been able to find anything regarding reference number. The case back shows The Star Case Company which manufactured cases for the US/Canadian market (which makes sense as the seller is in Canada) and the dial shows Swiss instead of Swiss Made which matches what the case back notes. Most of the ones I've been able to find similar to this, would have a Century dial but usually those would come with a cal 250/60 movement. Is there anything else I'm missing?


Thank you all in advance!

New photo. Closer look of the dial. Any thoughts on legitimacy? Meeting with the seller within the next couple of days.

Those are my concerns too. Not sure what kind of seller. Doesn’t seem to know much about the piece but I’m planning on asking a bunch of provenance questions and see the dial in detail. Any specifics on what to expect/look for on ‘galvanic’ vs ‘painted’ in person?

Also I haven’t seen those lugs in any other period Omega pieces, but would love to be wrong.

Which is correct for those structured "honeycomb" dials (and a few others).

If it was repainted, it was a pretty good job. I'd want close-ups without the plexi or, ideally, a pic from the back of the dial to be completely sure.

I certainly would not dismiss it only because it seems to be in great shape.

I was able to meet with the seller and check the piece myself. I think at this point my biggest concern is the fact that the seller doesn't seem to know much about the watch and mentioned that he had purchased it just about a month ago from a collector and wanted to sell because he prefers steel over gold. The condition of the watch seemed really good but whoever "serviced" it last did not do a good job of cleaning the dial and left some fibres (tip of hour 5 marker and south of hour 1 marker) as you can tell in the videos which doesn't give me the best feeling. At this point, I'm not feeling confident spending $850 on it.
