The Audemars Piguet Code 11.59 Selfwinding Flying Tourbillon reference 26396NR.OO.D002KB.01 is a 41mm luxury timepiece characterized by its contemporary two-tone construction. The multi-faceted case features an 18-carat pink gold bezel, lugs, and caseback, which contrast with a black ceramic middle section. This architecture is protected by a unique double-curved sapphire crystal that is convex on the inner surface and curved from 12 to 6 o’clock on the outer surface to create a distinctive optical effect. The watch is presented on a black textured rubber-coated strap with a calfskin lining and a matching pink gold folding clasp.
The centerpiece of this model is its smoked green enamelled aventurine dial, which is produced by mixing crushed aventurine glass with enamel and firing it at high temperatures to achieve a shimmering gradient effect that darkens toward the black lacquered inner bezel. It is powered by the in-house caliber 2950, a self-winding movement featuring a flying tourbillon at 6 o’clock that is cantilevered without an upper bridge for an unobstructed view. Operating at a frequency of 3 Hz, the movement contains 270 components and provides a minimum power reserve of 65 hours. The watch is water-resistant to 30 meters and includes hour and minute functions alongside the tourbillon.
General reviews of the Code 11.59 collection often highlight its technical sophistication and the complex hand-finishing of its case, which includes alternating satin-brushed and polished surfaces. While early iterations of the collection faced criticism for their dial designs, this aventurine version is frequently cited as one of the most visually striking and successful entries in the lineup. Collectors generally praise the depth and transparency of the fired enamel dial and the modern aesthetic provided by the ceramic case middle, though some critics find the 41mm diameter large for a dress-oriented piece and note that the minimalist hands can occasionally be difficult to read against the complex movement architecture.
