Patek Philippe 5004J Champagne Tachometre Perpetual Split 5004 18K Yellow RARE

The Patek Philippe Reference 5004 stands as a titan of modern high complication with a split-seconds chronograph and perpetual calendar, a technical achievement reserved for only the most discerning collectors. This particular example takes rarity to another level, featuring a gold case paired with an exceedingly rare champagne-colored tachometer dial— made by special request. At 36mm in diameter and 15mm thick, the 5004 remains wearable and discreet, in line with traditional Patek Philippe design codes. The case is in excellent condition, retaining original lines and curves. Powered by the CHR 27-70 Q manual winding movement—derived from the legendary Lemania 2310 base and extensively modified in-house—the 5004 embodies the apex of Patek Philippe’s mid- to late-20th century technical prowess. The split-seconds rattrapante complication, perpetual calendar display, and moonphase showcase the range and depth of Patek’s mastery. 5004s in precious metal case variants with unique dial executions are fiercely coveted on the secondary market, especially those made as bespoke commissions. Part of Patek Philippe’s esteemed Grand Complications line, the 5004 is widely recognized as a landmark in the timeline bridging classical and modern haute horlogerie. Such dial variations are almost never encountered, making this piece a centerpoint for any serious assemblage. The watch is accompanied by the original solid caseback, Patek Philippe box, and original certificate dating the watch to 2001. According to our research, this is likely to be the 5th 5004J ever made, with the movement number ending in XXX'505, with XXX'500 being in the Patek Philippe museum.
