About this reference
The Audemars Piguet Royal Oak reference 5402 in stainless steel and 18k yellow gold was produced during the mid-to-late 1970s and early 1980s. Collectors value this reference as the original "Jumbo" execution, featuring the ultra-thin Calibre 2121 movement and a 39mm monobloc case construction. This specific two-tone configuration is historically significant because it includes Gérald Genta’s personal timepiece, which he customized with a unique 18k gold bezel. The dial typically features the "Petite Tapisserie" pattern with the "AP" logo positioned at 6 o’clock on earlier A-series and B-series examples. On the secondary market, standard two-tone 5402 models generally trade between $40,000 and $80,000 depending on condition and provenance. A notable auction result occurred in 2022 when Genta’s personal 5402 sold for approximately $2.1 million, establishing a record for the reference and highlighting the premium placed on unique historical ownership.
