Yeah, I pretty much disagree completely with the original poster. The gen PO is one of the nicest watches I've ever owned -- and I've had/ some beauties. Dead on accurate, winds unbelievably smoothly, great AR. The bezel is bulletproof. Far superior IMO to the Submariner irrespective of the price difference, which seals the deal for me.
Having had a fully (I mean, fully) modified UPO, I can say the gen is far and away better. Keep this in mind, as well: to fully modify a UPO, you're going to need near as makes no difference to $1000. I picked up my nearly new PO for $1700. Factor in consistent build quality, factory warranty and service, accuracy and reliability of the co-axial movement, the decision for me was clear.
