If they were going to do a dial that special, why would they use a De Ville for it? Sort of like making a limo out of a Camry.

 

I have a feeling that it might be correct. If it's a redial they put a lot of effort into it, even putting the sigma markings on the bottom of the dial.

 

Does not look like an original dial to me. Besides we are making the assumption that OM means it is solid gold - easy enough to print those letters on any dial.
Fonts look off to me - the two spines of the letter A in omega don't even look even for example. Also the omega dials don't have the swiss made font color different from the rest of the dial lettering.

 

It's not just the "Swiss Made". The entire minutes track is white, while the logos are black. Not like any Omega dial I've seen from any era.

Is that in fact an engraved dial? The hour markers look like they're flat attached to the dial at all points as if there's no texture or uneven-ness to the surface, unless I'm seeing things? I mean on stepped dial constellations you can see markers sitting up slightly above the stepping even though its only very finely engraved, and the swiss made text in the stepping always looks like its following the contour of the engravings, this looks more two dimensional, unless I'm just not seeing it :\

 

This is one of the problems with trying to judge a three dimensional object from a a 2-D photo. My guess is that the finish really is 3-D with the priniting sitting on top. This isn't too tough to do using modern printing techniques.

If the work was done properly, the holes for the dial markers would have been protected during the process and everything soldered back into place at the end. However, on this dial it would not surprise me if the markers were merely glued on to the dial after the paint work was complete. The buyer could be in for a nasty surprise in a few years when the glue deteriorates and the markers begin to fall off.

The work looks that shoddy,

Thanks for the info! I thought I remembered the pattern somewhere, but after looking again it's different from the OP's example. Here's a correct example:
