I do. But the two pieces are different.
The RO Perpetual is an ultra slim bracelet watch. It is not a "sport" watch - it is a watch which can be worn sporty, casual or with a jacket and tie. Its a RO, the design (to me and I own nautilus variants too) is more classic and has a better style and look to me than the Nautilus. I find the dial to be very clean and crisp, one which I admire. The movement is impecable, 2120 caliber. The feel of the RO on the wrist is that of a truly manly and comfortable watch.
The RO is not for sport at all. I wouldnt wear it near water. I wouldnt wear it in the water. I also have a number of other "Beater" watches which I wear for sport activities or swimming.
The 5980 is a Patek. It contains a wonderful movement. The black dial variant is very good looking to me - however, Who needs a $40K chronograph on a SS bracelet? This is the question I have asked myself. An Offshore does the same thing at half price. And, at least I dont mind beating up my offshore a little here and there. The 5980 is a Patek. I also have a 5960 so, to me the auto chrono function from PP is well handled in that watch.
If it were me, and I am assuming that you own other dressier watches, and that the AP will not be your "only" fine watch - I would say go for the trade. Obviously, the 5980 is not doing it for you, even though its a Patek. That is ok. It happens. If you are not happy with the watch, and dont want to reach for it - let it go.
Now, if the 5980 is your only PP, and the rest of your collection is Daytona's - I get it, and I'd say keep the patek. As long as you understand that the RO, if you are buying new, you are overpaying and the PP, well, its a Patek.
Was that helpful at all?
Either way - you have the type of problems I wish everyone had
Good Luck -
