Complications, 5328G-001, White Gold, 2026

The Patek Philippe 5328G-001 brings an eight-day power reserve to the Calatrava collection, allowing the watch to run for over a week without winding. Released in 2025, the reference pairs a textured blue dial with a white gold case featuring the traditional Clous de Paris hobnail pattern around its sides. The power reserve indicator at 12 o’clock makes it easy to monitor the remaining running time, while the day and date are neatly arranged at 6 o’clock.

Developed specifically for this reference, the manually wound calibre 31-505 uses two mainspring barrels to maintain consistent performance throughout its eight-day running period, with an additional ninth day held in reserve. The movement also incorporates an instantaneous calendar mechanism, ensuring the day and date change together precisely at midnight rather than advancing gradually.
