Calatrava 8-Day White Gold / Blue

The Patek Philippe Calatrava 5328G-001 debuted in 2025 as a manually wound model combining an eight-day power reserve with instantaneous day and date displays. The watch is housed in a white-gold round case measuring 41 mm in diameter with a thickness of 10.52 mm. Water resistance is rated to 30 metres. The entire circumference of the caseband is decorated with the maison’s hobnail guilloché pattern. A sapphire crystal case back is fitted. The dial is finished in textured blue with a black-gradient rim. Applied white-gold numerals and white-gold syringe-shaped hour and minute hands are coated with white luminescent material. The display includes an instantaneous day indication in an aperture, an instantaneous date by hand, a power-reserve indicator at 12 o’clock, and a small seconds display at 6 o’clock. Powering the watch is the manually wound calibre 31-505 8J PS IRM CI J. The movement measures 32 mm in diameter and 5.05 mm in thickness, comprises 256 components and 28 jewels, and operates at a frequency of 28,800 semi-oscillations per hour (4 Hz). Twin barrels provide a minimum power reserve of 192 hours (eight days). The movement incorporates a Pulsomax escapement in Silinvar®, a Spiromax balance spring, and bears the Patek Philippe Seal. The watch is delivered on a blue calfskin strap with fabric pattern and cream stitching, secured by a patented triple-blade white-gold fold-over clasp. An additional grained taupe calfskin strap is included.
