About this reference
The Audemars Piguet Royal Oak reference 5402BA was produced from 1977 through the early 1980s as the first precious metal iteration of the original Jumbo design. Collectors prioritize this reference for its 39mm "Jumbo" monobloc case construction and the ultra-thin Calibre 2121 automatic movement. Unlike modern solid gold versions, the 5402BA features a specific vintage aesthetic defined by its "Petite Tapisserie" dial and a thinner profile than later iterations. Production was limited, with approximately 736 units manufactured, making it significantly rarer than its steel counterpart. On the secondary market, prices typically range from $120,000 to over $200,000 depending on the presence of the "A-series" serial number or original paperwork. A notable production detail is the existence of the "Jubilee" variant or pieces with the "AP" logo at six o'clock, which command premiums at international auctions due to their proximity to the original 1972 design layout.
