Patek Philippe. A very fine and rare platinum perpetual calendar split seconds chronograph wristwatch with moon phases, original Certificate and additional case back

With Patek Philippe Certificate of Origin confirming the sale of the present platinum watch with Arabic numerals and a diamond between the lugs of 0.02 ct. on 23 November 2010. Accompanied also by additional platinum case back, platinum and wooden setting pin, instructions, tag and original fitted veneered presentation box and outer packaging. Furthermore delivered with a Patek Philippe leather-bound folder containing details of reference 5004.

The present platinum reference 5004 is in excellent overall condition and comes complete with its original accessories from second non-glazed case back to Certificate of Origin. Like other platinum examples it features a diamond between the lugs at six o'clock. The watch has never been offered at auction before.

Reference 5004 is already considered a modern classic. In essence, this reference derives its features from the reference 3970, which itself is based on the legendary reference 2499. However, reference 5004 steps up a gear in terms of complication by boasting the highly complex split seconds function. Reference 5004 is roughly one millimeter larger than reference 3970 and also easily recognizable by its oversized split-seconds pusher in the crown.

Production of reference 5004 was launched in 1994 and is today discontinued. Patek Philippe replaced it with two other much slimmer and smaller platinum split-seconds chronograph references: the cushion-shaped reference 5951 released in 2010 with in-house calibre CHR 27-525 PS Q and the reference 5204, released in March 2012 at the Basel Fair with in-house calibre CHR 29-535 PS Q.

Reference 5004 is illustrated in Patek Philippe Wristwatches by Martin Huber & Alan Banbery, second edition, p. 312.
