I still have a closed factory case from the famous first gen 007. Those are as rare as the real 007.
It has the correct he valve kinda between 10/11 oclock, correct crown guards and serial number on the rear lugs.
If anyone wants, I would trade the case for a GMT watch or something simlar.. already have a few SMP of different versions.
The biggest give away on the current case is the he valve position and the crown guards.
