The Patek Philippe reference 5326 is one of the manufacture's most innovative contemporary travel watches, combining the practical Annual Calendar with the renowned Travel Time complication in an elegant Calatrava-inspired case. Introduced in 2022, the 5326 is powered by the automatic Calibre 31-260 PS QA LU FUS 24H, integrating dual-time functionality with Patek Philippe's patented Annual Calendar, allowing the wearer to display local and home time while automatically accounting for months with 30 and 31 days. The dial is distinguished by a textured charcoal-grey finish with luminous Arabic numerals, while day, date and month are displayed through three apertures, complemented by a moon phase, small seconds and day/night indicators for both time zones.

Produced exclusively in white gold, the reference 5326 features a distinctive hobnail-patterned case band inspired by vintage Calatrava models, paired with interchangeable calfskin straps that enhance its versatile character. Combining advanced mechanical innovation with contemporary styling and exceptional craftsmanship, the 5326 has become one of Patek Philippe's most admired modern complications, celebrated for its practicality, technical sophistication and unique interpretation of the classic travel watch.
