A simple calatrava or one of the 1950 pieces are so sublime and personally are what PP is all about.
Yes I would long for a 3970 or a 3940 or one of the 1516 but I am always satisfied and contented with my simple pieces
I am alwys looking for another holy grail piece, as a collector I do not really think I will ever "finish", when that happens it is time to get rid of the watches and move onto something else, never gonna happen!
