Audemars Piguet Royal Oak Minute Repeater Supersonnerie 26591TI

About This Watch

The Audemars Piguet Royal Oak Minute Repeater Supersonnerie 26591TI in titanium represents the absolute summit of acoustic watchmaking combined with the iconic Royal Oak design. The Supersonnerie technology, the result of eight years of research and development in collaboration with the Swiss Federal Institute of Technology in Lausanne (EPFL), achieves unprecedented sound clarity and volume in a wristwatch. The minute repeater chimes the hours, quarter hours, and minutes on demand via a slide mechanism on the left side of the case. The caliber 2937 features a revolutionary soundboard system inspired by musical instrument construction, with gongs attached to a specifically shaped membrane that amplifies and projects the sound outward from the caseback. The titanium case was chosen both for its lightweight comfort and its acoustic properties. The blue "Grande Tapisserie" dial maintains the Royal Oak's familiar aesthetic despite the extreme mechanical complexity beneath. A minute repeater is traditionally considered the most difficult watch complication to execute, requiring the highest levels of hand assembly and acoustic tuning. The Supersonnerie edition takes this further with patented innovations that produce one of the loudest and most musical chimes ever heard from a wristwatch. This watch exists at the intersection of engineering, art, and acoustics.
