Constellation redial question.

The other day my Dad handed me his Omega and said he needed to get it serviced. I was going to take it to a local watch repair shop but I noticed that the dial is not quite right, I cant find any other Constellation that looks like it. The watch was a gift from my Grandmother to my Grandfather in 1963. The only thing I can think of was that at some point my Grandfather must have taken it to someone to have it cleaned or refurbished and they either re-painted the dial or used a replica. I have not had the case back off so I cannot verify the movement, I highly doubt my Grandmother was sold a replica back in '63.

Any of you ever see a Constellation like this one?

Can confirm this is a redial. Case has also been polished up a bit and the crown has been swapped. So you're probably correct that it was done during a previous service.

Its a real omega with a redial. You could get it redialed again with something closer to the original, if that's important to you. I may be getting sentimental in my old age, but inscribed jewellery gifts between people who profess love is very special.
