for the same price as 1 Patek 5980 realy bothers me
These RO can be found at your AD easily with a nice discount whilt the 5980 can't. The 5980 will cost you 3 times the AP RO. I never really understood the price of the 5980. I like the watch and the brand but the Nautilus chrono is imo way overpriced. I would go for the RO, it is a very nice watch and it's a bargain. You could buy a black and a white one and still have some money left for another great watch
RO=1972
Nautilus=1976
and both were designed by Gerald Genta
