Patek Philippe continues to redefine daily elegance with the new Calatrava 5328G. At its heart beats the brand-new caliber 31-505 8J PS IRM CI J, a manually wound movement engineered for precision and endurance. Featuring an eight-day power reserve—with a ninth day in red as a winding cue—and instantaneous day and date displays at 6 o’clock, this caliber brings together classic architecture and advanced horology, including the Pulsomax® escapement with Silinvar® components, straight from the Patek Philippe Advanced Research program.
The 5328G’s vertically aligned indications sit on a textured blue dial with a black-gradient rim, accented by luminous white gold numerals and hands. The dial’s unique layout houses the small seconds, day, and date in perfect harmony, making the display both intuitive and artful. The 40mm white gold case features the maison’s signature hobnail guilloché along the band, while the sapphire caseback reveals a movement finished to Patek Philippe’s exacting standards.
Completing the offering are two quick-change calfskin straps—navy blue calfskin with a fabric texture and cream stitching and a taupe-grained alternative—secured by a newly patented triple-blade folding clasp. With its blend of functionality, mechanical innovation, and looks, the Calatrava 5328G is a modern classic built to meet the rhythm of modern life, yet steeped in the timeless language of fine watchmaking.
