Thanks to mwf I am much informed on watches. But it is also the beginning of this expensive hobby. I am taught to stay with 7 and I have 6 now after 2 years of indulgence. Since the topic is 'next' holy grail, I think I shall go for the Daytona Rolex.
Of course top on my list are PP nautilus and Rolex Yatchmaster 2 (blue ceramic). I think the new yatchmaster 2 is the mother of all Rolexes. Well, like they say in Hollywood, dream on, dream on. Someday dreams do come true!
