Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Extra-Thin (RD#3) Steel Blue Dial 39mm Ref. 26670ST.OO.1240ST.02

The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Extra-Thin (ref. 26670ST.OO.1240ST.02) continues the evolution of the RD#3 series launched for the Royal Oak’s 50th anniversary—merging the purest Jumbo lines with an ultra-thin flying tourbillon for the first time in the 39mm format. Crafted in stainless steel with the familiar integrated bracelet and stepped octagonal bezel, the case remains a svelte 39mm across and measures just 8.1mm thick, preserving the signature proportions of the original 5402. The smoked blue dial features the “Petite Tapisserie” pattern, subtly opened at 6 o’clock to reveal the cage of the flying tourbillon. Powering the watch is the innovative calibre 2968—a 3.4mm-thick automatic movement that offers a 50-hour power reserve and beats at 3Hz. Water-resistance is rated to 50m. By combining the most iconic Royal Oak design language with one of watchmaking’s most intricate complications in such a compact profile, ref. 26670ST.OO.1240ST.02 demonstrates the maison’s technical maturity—delivering complication without compromise to Adrian Genta’s original proportions.
