Combining a split-chronograph with perpetual calendar & moonphase, the 5004 is such a serious grand complication that Patek were only able to make 12 movements per year during its production run. Just back from a full service with Patek Philippe and under their 2 year warranty this extremely rare and important horological masterpiece is in 'like new' condition and perfectly sized at 36mm. Exquisitely classic with its 18ct yellow gold case, silver dial, applied gold numerals and brand new black alligator strap we are pleased to present this with its Patek service papers, extract from the Patek Philippe archives confirming its 2005 manufacture and sale, and its polished wood Patek Philippe box.
