Grand Complications Men’s - 5270/1R 41 mm, 18k rose gold, CG 29-535 PS Q hand-wound manufacture caliber with moon-phase display, chronograph function, and perpetual calendar | Reference Number PP330143

Patek Philippe began producing chronographs with a perpetual calendar far back in 1941. Since then, these timepieces have been some of the manufacturer’s most coveted watches. Here, an ebony-black dial presents this family’s classic face through its layout, featuring the day of the week and month in a double aperture at twelve o’clock and a hand-type date display at six o’clock, with integrated moon phase. Despite its eleven indicators and tachymeter scale, the watch still impresses through its cleanness and pleasing readability. Ticking inside the 5270/1R-001 is a hand-wound CH 29-535 PS Q caliber in a 41.0 x 12.7 millimeter case made of 18k rose gold. The caliber consists of 456 parts and yet is only 7.0 millimeters thick.
