The Patek Philippe reference 5109 is a distinguished member of the Gondolo collection, drawing inspiration from the manufacture's celebrated shaped watches of the early twentieth century. Introduced in the early 2000s, the 5109 features a graceful tonneau-shaped case that reflects the Art Deco styling long associated with the Gondolo family. Powered by the manually wound Calibre 215 PS, it combines classical proportions with exceptional movement finishing, offering a refined dress watch that stands apart from Patek Philippe's traditional round Calatrava models. Its elegant dial, elongated Roman numerals and balanced design showcase the manufacture's enduring mastery of shaped watchmaking.

Produced in precious metals including yellow gold, white gold and rose gold, the reference 5109 represents Patek Philippe's continued commitment to preserving the artistry of non-round case design. Together with references such as the 5124, 5200 and the commemorative 5500 Pagoda, it forms part of the modern Gondolo collection, celebrating the brand's rich Art Deco heritage while incorporating contemporary mechanical craftsmanship. Today, the 5109 is admired for its timeless elegance, beautifully finished manually wound movement and its important role within Patek Philippe's family of shaped dress watches.
