Hi, can I get some advice on this watch. I had bought it on a whim on eBay, and I'm not sure of it's authenticity. The seller had extremely good feedback, but I'm still not convinced. What I believe to be a serial number on the quartz doesn't match up with those online, it looks to be 10 digits long, not 9.
Any advice on what exactly this is and if it is real, would be greatly appreciated.

 

I wish I had a dime for every poster who bought a watch before check if it's real.

 

Unfortunately this is my first experience in buying any sort of nice watch and I wasn't aware of the dangers of fakes. Forgive my inexperience, any constructive feedback would be great

 

It's a real Omega. Strange patina to the date wheels vs the shiny dial.
