Audemars Piguet’s Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.01 marks the icon’s 50th Anniversary with refined ergonomics and that unmistakable octagonal bezel in stainless steel. Its blue “Grande Tapisserie” dial features a tri-compax layout with luminous markers and a color-matched date between 4 and 5 o’clock, all framed by a 41 mm steel case rated to 50 m and paired with the integrated Royal Oak bracelet for signature comfort and presence.
Inside beats AP’s in-house Calibre 4401, an integrated flyback chronograph with column wheel and a robust 70-hour power reserve. A sapphire caseback reveals the special 50th Anniversary oscillating weight—an elegant nod to five decades of design leadership. Sporty, precise, and unmistakably Royal Oak, this is the modern chronograph for collectors who demand heritage with cutting-edge performance.
