But what exactly is this Royal Oak ? Those in the know will point out that Audemars Piguet does not produce its cult model with a small seconds movement. Connoisseurs will add that it no longer offers it in steel with an alligator leather strap. And they are all correct, given that ref. 26591PT is not what it might seem at first sight. The key to this mystery lies in noting the slight protrusion on the left side of the case and identifying it as minute repeater slide bolt. After a lengthy hiatus, the Royal Oak is once again rendered audible, albeit not with the help of a historical movement. After Royal Oak Offshore Concept and Jules Audemars models, this grand classic with its octagonal bezel has in turn been equipped with a Supersonnerie movement. The 2959 caliber is coupled with resonance table placed between the movement and the back, as well with a special caseback, together serving as a natural amplifier. The Supersonnerie therefore features acoustic intensity combined with clear and sustained sound quality. So much so that Audemars Piguet has taken the liberty of fitting it inside a case made of platinum, a soft metal that absorbs sound waves. A paradox, a luxury, an acoustic performance.
