Well for my input, I have had the FC Peking to Paris and the Oris Diver and here's my views.
The FC is a truly beautiful watch, quite rare and feels great, a tad small for me personally but i have 8 inch plus wrists.
The Oris diver is indeed a great watch also and more correct size wise for me, I had it on rubber however it never really felt special, not as special as the FC.
Don't know about the other one.
