The Audemars Piguet Royal Oak Selfwinding Ref. 15402OR.ZZ.D003CR.01 is a breathtaking expression of haute joaillerie and iconic design, transforming Gerald Genta’s legendary 1972 octagonal masterpiece into a scintillating work of art. This exceptional 41mm timepiece is crafted from warm 18K rose gold, with the case and its signature octagonal bezel set with 166 brilliant-cut diamonds totaling approximately 3.09 carats, their flawless brilliance framing the dial in spectacular fashion . The dial itself is a showstopping canvas of light, completely pavéd with 345 additional 8/8-cut diamonds (approximately 1.07 carats) , meticulously arranged to create a seamless, glittering surface that replaces the traditional “Grande Tapisserie” pattern with pure, unadulterated sparkle . Despite its dazzling exterior, the watch retains the collection’s refined proportions, measuring just 9.8mm in thickness . Visible through the sapphire crystal caseback is the legendary in-house automatic Caliber 3120, a movement comprising 280 parts that beats at 21,600 vibrations per hour and delivers a robust 60-hour power reserve . The movement showcases Audemars Piguet’s meticulous hand-finishing, including Côtes de Genève, circular graining, and a 22-carat gold oscillating weight. The watch is paired with a luxurious and comfortable black alligator leather strap, which stands in elegant contrast to the diamond-set rose gold case and is secured with an 18K rose gold folding clasp, also set with diamonds . With 50 meters of water resistance and sapphire crystals on both sides, this Royal Oak is not merely a timepiece but a wearable masterpiece of gem-setting artistry and horological excellence, destined for the discerning collector who demands the perfect synthesis of mechanical prestige and radiant luxury. Key specifications: 41mm 18K rose gold case with diamond-set bezel; fully pavé diamond dial; Caliber 3120 automatic movement; 60-hour power reserve; black alligator strap with 18K rose gold diamond-set folding clasp; 50m water resistance; sapphire crystal front and back; diamonds totaling approx. 4.16 carats .
