Omega ref 2646-2648

Hi all,

I found this Omega with a dial i have not seen on this particular model before. The watch is described as fully original and unpolished by the seller but i have doubts. First the case, it looks very shiny, looks like it has gotten a polish treatment right? Second is the dial. Did Omega make this reference with this dial variation? Im thinking it could be a service dial or perhaps a dial for a specific market. Does anyone here have a similar or have seen another example?

The dial doesn't look original to me the "Seamaster" font seems odd.

Yeah it’s a redial. The fonts are off and the text doesn’t appear to be gilt. Lume is missing from the markers and either the hands are replacements or the dial is a replacement per observation from @Dan S .

Edit: it’s also been polished

I actually thought the same about the hands. They have lume but the dial has not.
The redial was not as obvious to me. I was leaning more towards that the dial had been replaced
