The present Audemars Piguet Royal Oak Tourbillon Extra-Thin Openworked reference 26518ST.OO.1220ST.01, offered as a complete full set and dating to 2017, is an exceptionally rare and technically impressive example of Audemars Piguet’s modern haute horlogerie. Produced in a highly exclusive limited edition of only 100 pieces worldwide, this model stands among the most sophisticated contemporary interpretations of the Royal Oak. Housed in a 41 mm stainless-steel case, the watch appears to be unpolished and is preserved in excellent overall condition. It shows only very light signs of wear consistent with careful use, with no notable dents or major scratches. The case and integrated bracelet retain crisp lines and sharp finishing, underscoring the careful ownership and outstanding preservation of the piece. The defining feature of this reference is its breathtaking openworked dial, which reveals the ultra-thin hand-wound tourbillon movement in full architectural detail. Meticulously skeletonized and finished to the highest standards, the movement showcases traditional haute horlogerie techniques such as hand-beveling, satin brushing, and polished anglage. The tourbillon at 6 o’clock serves as both a technical centerpiece and a visual focal point, reinforcing the watch’s status as a flagship complication within the Royal Oak family. Executed in steel—a material rarely associated with such high complications—the watch combines everyday wearability with extreme mechanical refinement. The ultra-thin construction further emphasizes the technical achievement and the elegance of the overall design. Delivered as a full set, the watch comes complete with its original large presentation box with key, documentation, and accessories, enhancing its desirability and long-term collectability. Rare, mechanically extraordinary, and preserved in superb condition, this Royal Oak Tourbillon Extra-Thin Openworked represents a unique opportunity to acquire one of the most exclusive and impressive modern Audemars Piguet creations in stainless steel.
