The Patek Philippe Grand Complications reference 5372 is a perpetual calendar chronograph, distinguished by its highly complex movement and precious metal construction. This reference is part of Patek Philippe's Grand Complications series, representing a pinnacle of traditional horological artistry and technical achievement.

The design integrates the perpetual calendar and chronograph functions in a refined and legible manner. The reference 5372 features a platinum case measuring 38.3 mm in diameter and 12.93 mm in thickness. It houses the manual-wind caliber CHR 27-525 PS Q, a movement known for its intricate construction and precise operation, which was also utilized in other notable Patek Philippe chronographs. The watch is fitted with a sapphire crystal, providing clear visibility of the dial and offering scratch resistance. The movement's finishing is executed to a high standard, visible through the case back.

The 5372 is available in right-handed versions, with a distinct left-handed variant (ref. 5373) sharing the same base movement, rotated for its specific configuration. Its limited production and technical sophistication position it as a significant piece for serious collectors of high horology.
