Beautiful watch.
Love the rare blue dial

 

At the risk of raining on any parades, the heavily refinished back suggests some preparation on this, are we sure it isn’t a S Korean dial repaint? Was that shade of blue available originally. Note the contrast between fade on the date wheel and Tippex white hands. I suspect that has seen a comprehensive going over.

 

The case has certainly been heavily polished. It's not as bad as some refinishing jobs but it would stop me from buying.

The price wasn't huge so if you're happy that's all that matters.

 

I am not an expert on 70s Omegas, but it looks ok to me. The broken off lume plot at 3 o'clock points to originality, IMO. The blue colour looks alright too.

 

Found another blue dial like that. Looks like my fears for the dial are unfounded. The case has definitely been worked on though, particularly the caseback. Not the end of the world, it is attractive and wasn't a silly price, unlike the one in the link:

Here's an untouched back:

 

Yup I think the dial is actually ok.
