A pop quiz -- I love it!
I'm squarely in the newbie camp, so I took a shot before cheating and scrolling. I saw the hands are clearly wrong (too long, mismatched gold), the Omega logo is far from centered, the crosshair lines look too thick, minute markers look too far outboard, and the crown is wrong. It's also not a pie pan in the sense the term is used on OF, at least. Lugs look good to me. I didn't catch the case issues at all, but I didn't research comparables before compiling this list.
Oh, and "Chronometer" is spelled wrong. ;-)
