  • Catalogue Essay

    Patek Philippe’s companion reference to the sporty 2508, the 2509 notably differs with its feature of subsidiary seconds, but they are otherwise identical: the sculptural lugs, broad, sloping bezel, screw-down caseback, and anti-magnetic dust cover on the movement.

    The reference was in production from 1950 to the late 1960s and features an evolution: early versions are fitted with lozenge and triangular indexes, such as the present example, and later versions with lapped indexes and beady minute divisions. The caliber powering the model undergoes changes as well: while at the beginning it was cal. 12-120, it then became 12-400, and finally the anti-magnetic 12-AM400 at the very end of production. All cases of references 2508 and 2509 were made by Geneva-based casemaker Taubert, identified not only by the number 11 within a key, stamped inside the back, but also by its logo FB for, François Borgel, similarly found inside the case back.

    Further enhancing its desirability and transforming rare into extraordinary is the Hausmann signature on the dial of the present lot. Founded in Rome in 1794 by Ernst Hausmann and Hermann Frielingsdorf, Hausmann & Co. is one of Patek Philippe's most prominent retailers in Italy. To this day, Hausmann & Co. operate a Patek Philippe boutique on Rome’s prestigious Via dei Condotti. This reference 2509 is the only known Hausmann-signed 2509 in 18 karat pink gold, and one of only three total Hausmann-signed 2509s, with the other two executed in yellow gold.

    Not seen on the auction market in thirty-five years, this Borgel-cased, antimagnetic Calatrava is an exquisite example of the mid-century ingenuity of Patek Philippe. The rarity diptych of pink gold and double-signed dial that renders this reference 2509 possibly unique in the world of watches also makes it nearly irresistible to the most discerning of collectors.
