The watch appears to be real. The movement is an Omega 1140 which is based on the ETA 2890-2 with the attached Dubois-Dépraz chronograph module. 46 jewels and the gold plating are correct. The serial number would be usually be on the case back. Why not ask the seller for the serial number and a clearer picture?In original box. Bought 1975 at USAF store in Germany. 18k marked. Tiny Omega mark on face plastic. Gold finish (eta?) movement marked 1140 46j. Where is serial number? Highest jewel count for Omega auto?
By "gold plated" I was referring to the movement finish only. If the watch is indeed marked 18K then the gold parts of the watch would be solid 18K gold.Jimh and jmsrolls: Very astute observations. It is not marked 18K. Came from son of original owner who was in Germany for USAF in 1975. I did not
know Omega sold gold plated speedmasters. It must be a cheap one. (Did you mean mvmt.
The more I know the more I know how little I know.
