I recently received the 5th gen planet ocean from Paul. For your info, it's pretty much the same watch as the 4th gen. Despise the weak AR, wrong crown, incorrect bezel pearl.. It's the best 42mm out there. Unlike some of the picture I have seen, my omega logo sit perfectly where it should. One thing that bug me though are the two minor dust particle stuck inside the face. Even with all it faults, this is a beautiful watch.
For someone who have no experience opening watch, how hard would it be to open it up and clean the dirt off?
