Patek Philippe 5004P: Split-Seconds Chronograph Guide
Updated 2/17/2026
What Makes the 5004P Special
The Patek Philippe 5004P is a split-seconds perpetual calendar chronograph in platinum — one of the most complicated wristwatches Patek has ever produced in series. It combines three major complications: a rattrapante (split-seconds) chronograph that can time two simultaneous events, a perpetual calendar that accounts for month length and leap years until 2100, and a moon phase display. The 5004 was produced from 1995 to approximately 2011, with the platinum 'P' variant being the rarest and most valuable of the four metal options (also available in rose gold, yellow gold, and white gold).
Movement and Technical Details
The 5004P houses the caliber CHR 27-70 Q, based on a Lemania 2310 ebauche that Patek extensively modified and finished. It is a manually wound movement with 24 complications visible on the dial, a column-wheel chronograph mechanism, and a horizontal coupling clutch. The rattrapante function uses a second chronograph hand that can be stopped independently to record an intermediate time while the main chronograph continues running. Power reserve is approximately 55 hours. The platinum case measures 36.7mm in diameter — considered small by modern standards but perfectly proportioned for a dress chronograph. The case features a hinged dust cover on the back, typical of the 5004 series.

Market Prices and Auction History
The 5004P has appreciated significantly since discontinuation. At its original retail price of approximately CHF 350,000, it was already expensive — but the secondary market has pushed prices far higher. In 2023-2025, the 5004P has consistently sold at major auction houses for $300,000-$500,000, with exceptional examples (original dial, complete set, documented provenance) exceeding $500,000. The platinum version commands a 30-50% premium over the rose gold 5004R and yellow gold 5004J. The white gold 5004G falls between platinum and rose gold in value. Compared to its successor, the 5204P (which uses an in-house movement), the 5004P is actually preferred by many collectors for its Lemania-based caliber, which is considered smoother and more historically significant.

What to Look For When Buying
Condition is everything with the 5004P. The platinum case is softer than gold and shows wear more readily — look for sharp lugs and an unpolished case. The dial should be original: Patek used a silver-white dial on the platinum version with painted Breguet numerals, and the printing should be crisp and even. Check that all chronograph functions work correctly, especially the rattrapante — repairing a malfunctioning split-seconds mechanism is extremely expensive (often $10,000-$20,000 for a full service). An Extract from the Archives is essentially mandatory for a watch at this price level. The original box, certificate, and all accessories significantly impact value — a complete set can command a 15-25% premium over a watch-only example.

Frequently Asked Questions
How much is a Patek Philippe 5004P worth?
The Patek Philippe 5004P in platinum currently sells for $300,000-$500,000 on the secondary market, depending on condition, completeness, and provenance. Exceptional examples with full documentation have exceeded $500,000 at auction. The platinum version is the most valuable of the four metal variants.
What is the difference between the Patek 5004 and 5204?
The 5004 (1995-2011) uses a Lemania-based movement (CHR 27-70 Q), while the 5204 (2012-present) uses Patek's in-house caliber CHR 29-535 PS Q. The 5204 has a larger 40mm case versus the 5004's 36.7mm. Many collectors prefer the 5004 for its historical movement and more refined proportions.
How many Patek Philippe 5004P were made?
Patek Philippe does not publish production numbers, but experts estimate approximately 100-200 examples of the 5004P were produced during its 16-year production run. The low production volume, combined with the desirability of platinum, drives the significant premium over other metals.
