So far, everything looks decent, i.e. a minute track, what appears to be aged lume, Swiss being present, and print being relatively good. Additionally, I am perplexed that the caseback features the reference FX6282. Shouldn't that be a Globemaster?

 

photos of caseback, inside of caseback and movement? Higher-rez photo of dial?

 

Thank you for pointing out Norman Morris Co. You are exactly right! The caseback features the Arrow and the J

 

Looks like rotor has been rubbing on the caseback. Might be from a long time ago, or might be because of worn parts that are worn right now. Are you sending this to someone to get serviced after you feel comfortable with the overall originality of the watch? Also, it would still be useful to see better dial pics in higher resolution to determine if it has been refinished.

 

That Arrow and J symbol is Jonell watch case company - just one of several case makers that Omega contracted (ncluding Wadsworth, Star, and several others).
