百達翡麗，18K金萬年曆追針計時腕錶，配月相、24小時顯示及閏年顯示，型號5004J，約2011年製，附原裝證書、額外底蓋、盒子及外包裝

Deriving from reference 3970 which is the true and legitimate successor to the mythical reference 2499, reference 5004 embodies not only the essence of Patek Philippe's design legacy of the post war decades but also the savoir faire of their skilled master watchmakers who managed to add another highly complex mechanism to a traditional sized watch without disturbing its proportions. To many collectors, reference 5004 is one of the greatest wristwatches ever made and is often mentioned as the watch with the most promising future on the market.

Manufacture of reference 5004 was launched in 1994 and is today discontinued and replaced by reference 5204 released in March 2012 at the Basel Fair.

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