Hello to all OF members.
Few day ago i've got in my possession this Omega or not case
It is a franken case i believe.
1)The case back looks OK?
2)Middle part looks like 4 digit reference but which one?
Any help will be highly appreciated

 

Genuine case for an Omega Genève.

 

OK. Thanks JimInOz.
Which Geneve, 2903?
2903 has completely different lugs

Some more photos:

 

Agreed, that doesn't look like a 2903 case. It is presumably a mismatch of 2903 caseback and a random mid case that it happens to fit.

 

You're right, I didn't check the lugs properly .

This is a 2903.

 

More info please
