Royal Oak Flying Tourbillon, 26735SG.OO.1320SG.01, Sand Gold, 2025

Product Description

The Audemars Piguet Royal Oak Selfwinding Flying Tourbillon Openworked 26735SG is one of the most technically impressive modern Royal Oaks in production today. At 41mm, it retains all the sharp presence and unmistakable design language that has defined the Royal Oak for over fifty years, while showcasing some of the most advanced watchmaking and finishing currently leaving Le Brassus.

The case and bracelet are crafted from Sand Gold, Audemars Piguet’s newest proprietary alloy. Sitting between white gold and pink gold, it changes character constantly depending on the light, giving the watch a distinctive appearance unlike any other precious metal Royal Oak. More than a different colour, Sand Gold represents one of the manufacture’s most significant material innovations in recent years and has quickly become one of the most talked-about additions to the modern AP catalogue.

Then there’s the movement. Fully openworked and visible from every angle, the calibre transforms the watch into a showcase of contemporary haute horlogerie. Bridges, gears and finishing techniques are placed on full display, while the flying tourbillon at six o’clock appears to float within the movement itself. Unlike a traditional tourbillon, it is unsupported from above, creating a cleaner, more dramatic view of one of high watchmaking’s most revered complications. The result is a watch that combines architectural depth, technical complexity and visual drama in a way few modern sports watches can match.

For collectors, the appeal extends well beyond the Sand Gold case. The 26735SG represents the modern Royal Oak at its most ambitious, combining a flying tourbillon, openworked manufacture movement and one of Audemars Piguet’s most significant recent material developments within its most iconic collection. It is exactly the type of reference that defines a generation of Royal Oak collecting.

Our 2025 26735SG is presented in like new unworn condition, offered as a complete set, including a 2025-dated warranty card and the original Audemars Piguet box.
