Audemars Piguet 15500ST Royal Oak SS Silver Dial

The Audemars Piguet Royal Oak reference 15500ST, 15500ST.OO.1220ST.04 presents a compelling evolution of the iconic 41 mm Royal Oak lineage. Introduced in 2019, this iteration replaces the outgoing 15400 with a modern in‑house Caliber 4302, offering a 70‑hour power reserve and a higher 4 Hz frequency for enhanced precision. The stainless steel case retains the signature octagonal bezel and integrated bracelet, now slightly thicker at approximately 10.4 mm to accommodate the larger, more robust calibre. The silver “Grande Tapisserie” dial, with its refined guilloche pattern and clean peripheral minute track, reflects a subtle yet impactful refinement in design. The watch remains water‑resistant to 50 meters, balancing everyday practicality with luxury sports watch elegance. Collectors value the 15500ST for its technical maturity, movement architecture, and its role as a transitional piece bridging the classic Royal Oak aesthetic with contemporary horological innovation. The Caliber 4302’s generous power reserve and refined finishing make this model a compelling choice for discerning enthusiasts. Like New with Audemars Piguet box and undated papers.
