I want to pull the trigger on this Omega on ebay for quite a while, but I've been afraid. I've done a lot of reading and looking at various Omega constellations to see if this is real. The ref number and cal match up. The box, I believe is a Seamaster box though. The crown is not the decagonal one. I am not completely sure the strap/buckle is original either. The thing that gets me is that the "waterproof" that's usually on the back case is not there. I assume from over polishing? It does pass the MOY test and the "omega" symbol sketch on the glass. Just wanted the advice from the Omega experts as I am new to watch collecting and I would love to start with a vintage Omega Constellation. I wish they made designs like this today. Link is below.
