I have a watch I wanted to try and identify down to exact model and check it is not fake. Its an Omega Seamaster Cosmic 2000. Seems fine to me though I have a niggling concern! I'm going to get it opened up to be sure but can any Omega experts take a look for me? TIA!
Looks good - it's a reference 366.0825 which was introduced in 1972. It should have a caliber 1012 inside. Verify this when you have the case back off, and show us a pic of the inside of the case back and movement. The serial number on the caliber will tell us exactly what year it's from.
