Patek Philippe Perpetual Calendar Chronograph 5004R Black Dial Perpetual Calendar Split Chronograph 18K Rose Gold

About this watch

The Patek Philippe 5004 was introduced in the mid-1990s, pairing a perpetual calendar with a split-seconds chronograph in a classically sized rose gold case. This reference is powered by caliber CHR 27-70 Q, the manually wound Lemania-based movement Patek extensively reworked and finished to its own standard, with the added rattrapante mechanism and perpetual calendar module that define the model. The 5004 matters because it was Patek Philippe's first serially produced perpetual calendar split-seconds chronograph wristwatch, extending the lineage established by references such as the 1518, 2499, and 3970 into a more technically ambitious format. In 18K rose gold, the case retains the restrained proportions collectors associate with the reference, preserving the elegance that makes the 5004 distinct from later and larger successors. The rose gold case remains in excellent original condition, showing very few signs of ever being detailed in the past. Recorded on the Extract from the Archives, Patek Philippe confirms exchanging the original silver dial for a glossy black dial. The service completed in 2010 adds an important layer to the watch's story as the request was made shortly after the watch was delivered to the original owner. For collectors focused on complicated modern Patek Philippe references, the 5004 offers the appeal of the legendary CHR 27-70 Q architecture in one of the brand's most historically important grand complication formats.
