Ordered the 4th gen PO on Mar 7th. The first batch was sold out. So, Andrew shipped it on Mar 14th when he received the second batch. This is the best Omega rep I ever had. I am pretty sure it can trick most of the watch freaks.
The only obvious problem is the word "Planet Ocean" on the cover is not engraved. I checked the gen PO 42mm. The Omega logo is really close to the word. So I don't think it's flaw. The hour hand is about 1mm-2mm shorter than the gen. Nobody can notice this without comparing to the gen. Also, the omega logo and hands turn black when viewing from different angles. It's not obvious on the rep, but it does turn black
You never know when will the rep factory be closed. I suggest you to order one instead of waiting for the 5th generation. Sometimes they make it right, but sometimes they make it even worse.
Also check here for a comparison with the genuine PO:
