Product Description
The Audemars Piguet Royal Oak 15305ST Openworked Steel is a landmark piece in the evolution of the Royal Oak—one of the earliest modern openworked models produced in stainless steel, and a true collector favorite.
Housed in a 39mm stainless steel case, this reference preserves the classic proportions of the original Royal Oak design while introducing a fully skeletonized dial that reveals the intricate architecture of the movement. Every bridge and component is meticulously finished, offering a clear view into the craftsmanship that defines Audemars Piguet.
At its core is the selfwinding Caliber 3120, a highly respected in-house movement known for its reliability and refined finishing, including the signature 22K gold rotor visible through the caseback. The openworked design transforms the watch into a dynamic display of mechanical artistry—blending traditional horology with modern aesthetics.
Integrated seamlessly with the iconic steel bracelet, the 15305ST delivers both everyday wearability and high-end appeal. Discontinued and increasingly difficult to source, it stands as one of the most important openworked Royal Oaks for collectors.
