Royal Oak Offshore Selfwinding Chronograph

The Audemars Piguet Royal Oak Offshore Selfwinding Chronograph in reference 26420ST represents a pivotal evolution of the iconic Offshore lineage, featuring a refined 43mm steel case that strikes a balance between the original's boldness and modern wearability. Beneath its distinctive brown dial — a colorway that has resonated strongly with collectors — lies AP's calibre 4401 automatic movement, delivering an impressive 70-hour power reserve and COSC-level precision across 40 jewels.

Protected by sapphire crystal and rated to 100 meters of water resistance, the 26420ST is a statement piece that signals AP's commitment to both technical mastery and bold aesthetic identity. As a current production reference with full papers, this example offers collectors the assurance of authenticity and manufacturer warranty backing.
