百达翡丽，18K金万年历追针计时腕表，配月相、24小时显示及闰年显示，型号5004J，约2011年制，附原装证书、额外底盖、盒子及外包装

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.
