One of the great classics of the modern Patek Philippe catalogue, the reference 5004 was produced between 1994 and 2010. It is the first Patek Philippe serially-produced perpetual calendar chronograph wristwatch with moon phases - a set of complications rooted in the history of the brand, the first model made in series being reference 1518 launched in 1941 - with the additional split-second complication. Together with the reference 5070 and 5970, it is 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), 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 as a result of the split-seconds complication, granting it a more substantial wrist presence, while still remaining very elegant and understated.

Out of the four serially produced materials used in the 5004 – being yellow gold, white gold, pink gold, and platinum – pink gold appears to be one of the rarest, with total production estimated at around 200 examples. The present example is well-preserved and complete, accompanied by its original certificate of origin and additional solid case back. The model today is discontinued, however, it has achieved cult status amongst Patek Philippe purists as it perfectly combines the brand’s signature design, highest level of complications, and an uncompromising approach to quality.
