I have to declare a conflict in that I own a white dial 15300. As has been said, it is very striking and quite an "obvious" watch. The rotor in gold with the heraldic shields of the two founding families is a thing of beauty. I love too the waffle dial which offers something different.

Hwever, the bezel and bracelet do, as has been noted before, pick up scratches very easily but as a summer watch I think it is perfect.

All that said, I am growing to appreciate the nautilus more and more and could easily see myself with an annual calander on black leather strap as I age badly! Still, I guess I have to vote AP. an interesting comment above about the PP being a bit more stealth. I think that is correct.
