Audemars Piguet Royal Oak Two-Tone

About this reference

The Audemars Piguet Royal Oak reference 25402SA was produced during the late 1970s and early 1980s as a mid-sized alternative to the "Jumbo" models. This reference features a 33mm case constructed from stainless steel and 18k yellow gold, housing the ultra-thin quartz Calibre 2502. Collectors value this reference for its historical role in the brand’s transition during the Quartz Crisis and its adherence to the original Gerald Genta design language, including the integrated bracelet and octagonal bezel. The dial typically features the "Petite Tapisserie" pattern with an AP logo positioned at 12 o'clock. On the secondary market, the 25402SA generally trades between $12,000 and $18,000 depending on condition and the presence of original paperwork. A notable production detail is that this reference was among the first Royal Oaks to utilize a quartz movement, marking a specific era of technical experimentation for the manufacturer.
