Omega PO versus Rolex Submariner

[haakon59]

If you own both, do you favor one or the other? The PO has better lume, I realize, and the new co-axial escapement is a nice innovation too. How does the PO compare to Rolex in the way it feels on the wrist, i.e., is one heavier or bulkier than the other? Do you like both after wearing them or wind up heavily favoring one over the other? I am just wondering because I am considering both of these models--I hope it works out this summer. They are both great brands, great models, I think, but was wondering about your experiences. Thanks in advance.
