Audemars Piguet 26660ST.OO.1356ST.01 Tourbullon

An Architectural Marvel: The Audemars Piguet Royal Oak Tourbillon

In the rarefied air of haute horlogerie, few watches command attention like a tourbillon, and fewer still do so with the bold, iconic presence of a Royal Oak. The Audemars Piguet Royal Oak Selfwinding Tourbillon Extra-Thin reference 26660ST.OO.1356ST.01 represents the pinnacle of this fusion. It is not merely a timepiece; it is a declaration of technical prowess and avant-garde design, engineered for the connoisseur who appreciates the art of mechanics made visible.

Masterpiece of Skeletal Architecture & Technical Refinement

This watch is defined by its breathtaking openworked, or “squelette,” design. The craftsmen at Audemars Piguet have meticulously carved away excess metal from the calibre 2924 movement, transforming its functional components into an artistic composition. The result is a mesmerizing three-dimensional view into the heart of the watch, where every bridge, gear, and the star of the show—the tourbillon carriage—becomes part of the aesthetic.

The tourbillon, a complication originally invented to counteract gravity’s effects on accuracy, is elevated here to a kinetic sculpture. Positioned subtly at 6 o’clock, it performs its mesmerizing 60-second rotation, a constant reminder of the watchmaking genius contained within the slim 8.85mm case. This extra-thin profile, a marvel in a tourbillon watch, ensures the Royal Oak retains its legendary wearability and sleek silhouette.

Iconic Design Meets Uncompromising Craftsmanship

The watch’s identity is rooted in the Royal Oak’s legendary codes: the 41mm stainless steel case with its sharp, beveled edges, the integrated bracelet with its flawless satin-brush and polished finishes, and the iconic octagonal bezel secured by eight hexagonal white gold screws. The “Grande Tapisserie” dial pattern is reimagined here, etched directly onto the mainplate, creating a textured backdrop that plays brilliantly with light.

Every surface tells a story of hand-crafted finishing. Anglage (beveling) on movement edges, gleaming polished screws, and fine circular graining on the gears demonstrate a level of detail reserved for the finest Swiss watches. The use of 22-carat gold for the openworked rotor, visible through the sapphire case back, adds a touch of warmth and luxury to the technical panorama.

A Statement of Distinction and Lasting Value

Wearing this Royal Oak Tourbillon is an experience in appreciating micro-mechanical art. It is for the individual who sees beyond mere timekeeping to the centuries of tradition and years of innovation required to create such an object. It speaks of a discerning taste for understated complexity—a watch that is instantly recognizable yet reveals its true depth upon closer inspection.

As an exemplar of Audemars Piguet’s technical artistry within its most iconic collection, this timepiece transcends fashion. It is a legacy object, a testament to human ingenuity, and a sound horological investment. It is engineered not for a season, but for generations.
