One of the great classics of the modern Patek Philippe catalogue, the reference 5004 was produced between 1994 and 2010. It was the first Patek Philippe serially-produced perpetual calendar chronograph wristwatch with split-seconds – based on the iconic perpetual calendar chronograph models so intertwined with the history of the brand - now with the addition of a split-seconds complication. Together with the reference 5070 and 5970, it was the last Patek Philippe model to employ the “Nouvelle Lemania”-based calibre.

The aesthetics of the watch are based on reference 3970 (itself based on the iconic ref. 2499 and 158), with subtle differences: the dial features large Arabic numerals instead of baton markers most often found on the ref. 3970; the case is thicker and 0.8 mm larger because of the split-seconds complication, granting it a more substantial wrist presence, while still remaining very elegant and understated. While the model was cased in a variety of metals (pink gold, yellow gold, white gold, and stainless steel), platinum examples are incredibly rare. In addition, this dial is confirmed by the Certificate of Origin, adding another element of collectibility. It varies slightly from the -001, as the former has an opaline white dial, and the -021 bears a silvered dial.

Coming from the collection of an important collector, this fresh-to-market reference 5004 in platinum is accompanied by its full suite of original accessories, including additional solid caseback and setting pin. It has been recently unsealed from a factory service, and is exceptionally well-preserved.
