You can learn a lot by doing your own research. http://naligazone.com/index.php/data-watch/omega/caliber-2

 

Thanks for the link. Actually I have checked myself on omegawatches.com. They don't seem to match and that's why I am asking the experts here to see if it's possible there can be exceptions.

 

Anyone can give some advice? You help will be greatly appreciated. Thanks.

 

The case back is a match bb

 

Is or isn't a match? That's the first thing I should have looked at because I don't think the lugs are from either the 131.0015 or 16. I'm pretty sure that back does not go with the case.

 

Thanks for all the information. I really appreciate your help!

 

Likely a counterfeit case.

 

What is the reference number? It's very hard to make out, even on my macnificent Mac.

 

Looks like 131.015 on that back. Efauser carefully double checked on the 131.016 also. The Helvetia looks really bad anyways.

 

Thanks for all everyone's input. I finally decided to pass on this one.
