The Patek Philippe Reference 3448, nicknamed “Padellone” (Italian for “large pan”) by collectors, stands as a landmark timepiece in horological history. As the first automatic perpetual calendar wristwatch produced in series (1962-1981), this example stands among just 450 crafted in yellow gold from a total production of 586 pieces.
 
This exceptional 37.5mm “Padellone” features remarkably clear and deep hallmarks on the back of its angular lugs—a testament to careful preservation. Most importantly, this example comes complete with its original box, original sale invoice dated in 1970, original certificate and extra from the archive. For the discerning collector, this represents not merely a timepiece but a museum-quality investment with impeccable provenance.
