Audemars Piguet Royal Oak Perpetual Calendar

About this reference

The Audemars Piguet Royal Oak Perpetual Calendar reference 26579CE.OO.1225CE.01 entered production in 2017 and remains a centerpiece of the brand’s contemporary catalog. Collectors prioritize this reference for its full black ceramic construction, including the case, bezel, and integrated bracelet, which requires over 600 hours of finishing to achieve the signature brushed and polished surfaces. It features a "Grande Tapisserie" dial with four sub-dials, including a photorealistic moon phase and a week indicator on the outer chapter ring. Powering the watch is the ultra-thin self-winding Calibre 5134, based on the historic Calibre 2120. On the secondary market, prices typically fluctuate within the $225,000 to $300,000 range depending on condition and provenance. A notable variant is the "White Ceramic" 26579CB, though the black ceramic remains the foundational application of this material for the perpetual calendar complication within the Royal Oak collection.
