Pre-owned Audemars Piguet Royal Oak Selfwinding ref 15500ST.OO.1220ST.04 continues the legacy of one of the most recognizable luxury sports watches ever created. The 41mm stainless steel case is paired with the iconic octagonal bezel, secured by exposed screws, and an integrated bracelet that feels as architectural as it is refined. The silver-toned dial is decorated with the Royal Oak’s signature “Grande Tapisserie” waffle motif, a textured grid that catches the light in endless variations, complemented by white gold hour markers and hands filled with luminescent material. Visible through the sapphire caseback, the self-winding calibre 4302 offers a robust 70-hour power reserve and modern finishing that underscores AP’s technical prowess. With its screw-locked crown, glareproof sapphire crystal, and perfect balance of elegance and sportiness, the Audemars Piguet 15500ST for sale here embodies why the Royal Oak remains one of the most enduring icons in watchmaking.
