Patek Philippe Grand Complications 5204

Patek Philippe's Grand Complications 5204G-010 is a chronograph in a 40 mm white gold case measuring 14.3 mm thick. The case pairs with a sapphire crystal and an interchangeable solid caseback, and the sunburst navy blue dial carries a tachymeter scale for reading speed over distance. The manual-winding calibre CHR 29-535 PS Q drives a split-seconds chronograph and perpetual calendar, with day, month and moon phase shown through apertures and a hand-set date. Small seconds sit on the dial as well, and the hands carry a luminous coating for low-light legibility. The watch is fitted on a navy blue composite strap with a fabric pattern and red stitching, closed with a white gold folding clasp. Despite its complexity, the case still holds a 30 metre water resistance rating.
