Patek Philippe 5004P Perpetual Calendar Split Seconds Chronograph Platinum Black Dial

The Patek Philippe Reference 5004P stands as a crowning achievement in modern horology, introduced in the late 1990s as the brand’s first serially produced perpetual calendar with a split‑seconds chronograph. Crafted in platinum, this model houses the legendary Lemania‑based caliber CHR 27‑70 Q, a manually wound movement celebrated for its technical complexity and Geneva Seal finishing. With a 36.5 mm stepped case and a thickness of approximately 15 mm, it bridges the aesthetic lineage of the revered 3970 and 1518 while offering a subtly more robust wrist presence. Since this model is an earlier series and in platinum, the case and lugs are not as "sharp" as later platinum and gold examples, The black dial presentation—rare in this reference—adds a tuxedo‑like elegance to its functional sophistication, including moonphase, leap‑year, 24‑hour, date, day, and month complications. Produced in very limited numbers between approximately 1996 and 2012, the 5004P is among the rarest and most coveted of Patek’s modern grand complications. Its dual chronograph hands allow split‑timing, a feature that elevates its mechanical allure and collector desirability. This platinum variant, especially on alligator strap, is a pinnacle of both technical mastery and understated luxury, a true grail for seasoned connoisseurs.
