Audemars Piguet Royal Oak Chronograph 50th Anniversary Steel — Khaki Green Grande Tapisserie | Ref. 26240ST.OO.1320ST.04

Released in 2022 to mark five decades of the Royal Oak's unbroken dominance, the 50th Anniversary Chronograph in reference 26240ST.OO.1320ST.04 delivers the most historically resonant iteration of Genta's icon in a generation. The 41 mm stainless steel case — built to the exacting tolerances that define the modern Royal Oak — houses Calibre 4401, an integrated column-wheel flyback chronograph movement developed entirely in-house, beating at 21,600 vph with a 70-hour power reserve. Its architecture, visible through a glareproofed sapphire caseback, echoes the integrated construction philosophy that set the original 1972 watch apart from everything else.

The khaki green dial is the 50th Anniversary edition's most arresting statement: a shade that references the original 1972 'jumbo' Royal Oak's Petite Tapisserie while projecting an unmistakably contemporary character. Across its Grande Tapisserie guilloché surface, luminous Royal Oak hands sweep with authoritative precision, flanked by matching chronograph counters that maintain tonal harmony throughout. Applied steel hour-markers contribute dimension, while the integrated octagonal bezel — adorned with the collection's eight hallmark polished screws — frames the ensemble with the geometric confidence that has made the Royal Oak architecture endlessly reproduced and never equalled.

The matching stainless steel integrated bracelet — polished and satin-finished in alternating links — flows seamlessly from the case in the manner Genta envisioned, closing with the AP folding clasp and offering 50 metres of water resistance. At $64,999 with full box and papers, Ref. 26240ST.OO.1320ST.04 is the definitive steel celebration of a design revolution — jubilant, purposeful, and destined for collections assembled with serious historical intent.
