Patek Philippe Perpetual Calendar

About this reference

Produced between 1962 and approximately 1981, the Patek Philippe Reference 3448 was the manufacture’s first automatic perpetual calendar wristwatch. Collectors prioritize this reference for its Caliber 27-460 Q movement and its 37.5mm "Padellone" case, characterized by sharp, angular lugs and a minimalist dial layout featuring day and month apertures at twelve o'clock. Approximately 586 total examples were made, with the vast majority cased in 18k yellow gold. Secondary market prices for yellow gold specimens typically range from $300,000 to over $500,000 depending on condition and dial series. Four distinct dial variations exist, distinguished by the typography and the presence of a leap year indicator on later versions. A notable production rarity is the "Senza Luna" variant, which lacks a moon phase complication; one such example achieved a hammer price exceeding $1.1 million at a 2017 Christie’s auction.
