hi, i agree i have a pp51451j that i ware every day. i think is a beautiful and usable watch. why it is not the favorite of afficionados i do not know, but maybe because is more popular than the pc's. howver i also like the size of the 5146 most of the pc's are 37mm. maybe patek should cut the production of ac's so they bocome more collectible to afficionados. thanks jorge
