Looks more like a complete counterfeit, do you have a photo of the back? At the very least its been refinished.
Autobahn gold. Fakes typically sold at service stops. Marks on the back was made to fool people to believe they were 18k or more. 100% non Omega

WOW. $2388 final price. I did report it as fake and contacted seller, but he let the auction run it's course. Someone will not be happy.
This sold for the genuine chronograph, not for the fake Seamaster. I'm quite sure the winner knew it was fake.
Not sure but the chrono looks like a 321 from around 1960? If there is not too much wrong with that it may justify its price in full?
