Released early 2026, reference 26450 represents most significant upgrade in 38mm Royal Oak Chronograph history—introducing entirely new in-house Caliber 6401 after nearly three decades relying on modified Frédéric Piguet 1185 ébauche (rebranded as Caliber 2385). While the 41mm Royal Oak Chronograph transitioned to proprietary Caliber 4401 in 2022, its larger dimensions prevented adaptation to 38mm case, leaving smaller variant as last Royal Oak chronograph dependent on third-party movement archi
