Audemars Piguet Royal Oak Chronograph 50th Anniversary Steel — Black Grande Tapisserie Dial | Ref. 26240ST.OO.1320ST.02

The year 2022 marked half a century of the Royal Oak, and AP chose to commemorate the milestone with a chronograph that honours the past without being enslaved by it. Reference 26240ST.OO.1320ST.02 — the 50th Anniversary Royal Oak Chronograph — houses Calibre 4401 in a 41mm stainless steel case whose proportions echo the original Jumbo while incorporating the technical evolution of fifty years of refinement. The result is the most significant Royal Oak Chronograph of the modern era, bearing the anniversary designation with the quiet confidence of a manufacture that has nothing left to prove.

The black Grande Tapisserie dial is a masterclass in surface artistry: the larger hobnail squares that distinguish Grande from Mega Tapisserie create a bolder, more graphic texture that reads with exceptional clarity at a distance and reveals extraordinary craftsmanship under magnification. Luminous white-gold-tone hands — including the prominent chronograph seconds hand — sweep across the guilloché field with the precision of Calibre 4401's column-wheel chronograph mechanism. The date display at three o'clock and the integrated sub-registers maintain the clean integration AP demands.

The integrated stainless steel bracelet — its alternating brushed horizontal links and polished chamfered edges executing Genta's bracelet vision with modern finishing standards — connects to an AP folding clasp. The transparent sapphire caseback displays the Calibre 4401, a movement that combines a flyback function, column wheel, and vertical clutch within an architecture designed from the outset to integrate seamlessly with the Royal Oak case. Water-resistant to 50 metres, presented with box and papers: a definitive anniversary statement in steel.
