REF. 5039R-001, MOVEMENT NO. 776'355, CASE NO. 4'020'183, CIRCA 1999

Introduced in 1996, reference 5039 occupies a discreet yet significant place within Patek Philippe's lineage of perpetual calendar wristwatches. Produced until 2007, it offered a more ornate interpretation of the manufacture's celebrated perpetual calendar while retaining the elegance and restrained proportions that define the brand's complicated timepieces.

Presented alongside its sister model, reference 3940, the 5039 was manufactured in considerably smaller numbers, with research suggesting approximately 500 examples in yellow gold, around 400 in white gold, and only about 300 in pink gold, such as the present timepiece. While both references share the celebrated self-winding calibre 240 Q with 22K gold micro-rotor, the 5039 distinguishes itself through its richly detailed case architecture. A finely executed hobnail (Clous de Paris) bezel, elegantly downturned lugs, and more sculptural lines lend the watch a distinctive personality, combining technical excellence with enhanced decorative refinement.

Powered by one of Patek Philippe's most revered perpetual calendar movements, the calibre 240 Q enabled the manufacture to create an exceptionally slim and elegant complicated wristwatch without compromising reliability or functionality. Today, thanks to its comparatively low production, sophisticated case design, and timeless aesthetics, reference 5039 is regarded by collectors as one of the most refined and underrated perpetual calendars of the modern Patek Philippe era.
