**Royal Oak Perpetual Calendar** is a luxury wristwatch by [[Audemars Piguet]].

With this model Audemars Piguet wins the “Iconic Watch Prize” at the [[Grand Prix d'Horlogerie de Genève]] [[2025]].


===== Description =====
<blockquote>To mark the beginning of its 150th anniversary celebrations, Audemars Piguet unveils a new generation of selfwinding perpetual calendar movement, Calibre 7138, which for the first time ever, enhances user comfort by making the corrections of all functions possible via its “all-in-one” crown. The result? An intuitive complication that revolutionises the perpetual calendar experience while improving legibility.

This new movement makes its debut on a 41 mm Code 11.59 by Audemars Piguet in white gold, on two 41 mm Royal Oak models in a choice of stainless steel or sand gold.
