Invited by Audemars Piguet to curate and design the 40-year anniversary exhibition of the Royal Oak watch, Sébastien Léon conceived a traveling exhibition using design, photography, music and video to showcase one hundred exceptional timepieces and underscore the Manufacture's heritage and craft. The exhibition was composed of five display units called “fragments”, which could easily be shipped and assembled on site. Each fragment worked as a unique station focusing on one element of the Royal Oak story within the brand. In addition, Léon created a monumental organ-like sound sculpture with eletronic music based on the sound of the Royal Oak movements.

In addition Sébastien Léon invited video artist Davide Quayola, and photographer Dan Holdsworth to contribute to the exhibition's vision by each producing work about the origins of Audemars Piguet in their own medium. All artists were all assigned important additional commissions after the project was completed: Quayola with a new watch design, and Dan Holdsworth with a signature photo campaign to seal the whole brand identity.
