PF is a label that concentrates on Patek Philippe: public dealer write-ups under it cover the Nautilus 5711 in two dial colours and the 5726 annual calendar in several, plus one Roger Dubuis reference. It sits in the same buyer's shortlist as the other Patek labels, which is the practical point: a Nautilus listing can carry more than one name depending on the seller. Our own sample carries no listing under this label.
