The Audemars Piguet Code 11.59 26398OR.OO.D002CR.99 represents one of the most mechanically complex watches ever produced by the brand. Crafted in rose gold with an openworked dial, this 42mm piece integrates a rare combination of high complications—Grande Sonnerie with Supersonnerie technology, minute repeater, tourbillon, flyback chronograph, split-seconds chronograph, astronomical moon, moon phases, and large date—executed within a single reference. The multi-layered dial structure reveals the intricate orchestration of functions, surrounded by a smoked sapphire crystal flange and encased in AP’s signature double-curved sapphire. This model is not part of standard production and has only been made available to a highly select group of collectors. With its multi-complication construction and an exterior design that departs from AP’s sportier lines, the 26398OR.OO.D002CR.99 is a flagship expression of the Code 11.59 collection. It exemplifies the rare intersection of experimental engineering, acoustic innovation, and traditional finishing at the highest level of contemporary watchmaking.
