I've seen one Omega that has the NAIAD lock that didn't look perfectly perpendicular, or leveled. But it wasn't as far off leveled as the one you show there. Maybe a non-Omega tech opened up the case back for some reason and had screwed it back on either too tightly or not tight enough to make it line up straight.

It is a fake. Don’t buy it.

Actually, I don't think it is a fake.

 

Here is my PO with the NAIAD case back, for a comparison. Yours looks quite a way out. Saying that though, I did read over on the Omega forum that some had purchased Omega watches with the NAIAD case back, that were out of alignment, as yours is. They were genuine Omega watches, too.
Hope this helps.

 

Yes, there have been some swatches come out where the engraving wasn't lined up properly - Omega has rectified those free of charge from what I've seen.

 

Thanks for all the replies guys! I have seen other forum posts where people have not had theirs align properly and it was because the engraving itself was off a bit. Though this one is off more than any others I’ve seen. I’m going to go see it in person today. The same seller also has a silver dial Railmaster for sale on bracelet for $100 more than the dark dial and that one has the correct caseback alignment. I’ll have to compare the two in person and decide which way to go. Though the thought of having to send in the dark dial with the misaligned caseback seems for omega to take a look at seems very off putting.

Just FYI - I checked the serial number on the back of the watch you posted photos of...

Serial number: 89741982
Article ref: 22012402001001

Precisely the model it should be, so the chances of this being a fake are almost nil...

Cheers, Al

 

You know the seller, perhaps suggest you meet him at an AD with the watch to get it checked and buy hum lunch for the trouble. No harm, no foul.
