I have my doubts that it's even an Omega. But please, please, wait for some others that are much more knowledgeable. I have put my foot in my mouth too many times.
Looks like a Franken watch. Caseback from non-Omega watch (I have the same guy/script on a Lucerne of mine). Sent from my iPhone using Tapatalk
It is absolutely not an Omega. It is a (probably cheap) diver's watch that's had the dial repainted and the word Omega added. I hope you didn't give much for it.
Thanks all! I actually saw it and did not buy. They are going to call me tomm with what year it's from because they didn't know. That should be a real hoot!
