Nice review and pics! I too just picked up a 42mm "version 5" PO. It's a great rep.. hopefully the crown/tube will last a little while before replacing. (I hear they strip easily) Anyways.. went over to a friend's house who has the gen and held them side-by-side. The first thing we noticed was the pearl was slightly different, the caseback wasn't quite as nicely textured around the sea monster (wouldn't know unless side-by-side), HE valve was slightly bigger and the chamfering around the bezel was slightly different. In the wild.. it's hard to tell it's a rep unless you have the gen side-by-side. All-in-all.. great rep.
