Audemars Piguet Royal Oak Rose Gold — Blue Grande Tapisserie Chronograph, 50th Anniversary | Ref. 26240OR.OO.D315CR.01

2022 marked fifty years since Gerald Genta delivered his overnight sketches to Audemars Piguet and changed watchmaking forever. The house commemorated this milestone with a range of Royal Oak references that included the 26240OR — an 18-carat rose gold Chronograph in 41 mm that pairs the newly developed Calibre 4401 flyback movement with a blue Grande Tapisserie dial of extraordinary chromatic richness. Released as a jubilee reference, this piece carries both technical and historical significance in equal measure.

The Calibre 4401 flyback chronograph, developed entirely in-house, features a column-wheel, vertical clutch and 70-hour power reserve — specifications that place it among the finest integrated chronograph calibres in Swiss watchmaking. On the 26240OR, it operates beneath a blue dial whose guilloché pattern has been recut with the precision of modern CNC tooling calibrated to Genta's original proportions, producing a surface that is simultaneously faithful to the archetype and technically superior to every previous iteration. Luminous hands and the exhibition caseback complete a presentation that rewards sustained examination.

Supplied on a leather strap with AP folding clasp — a bracelet choice that emphasises the rose gold's warmth — and presented with full box and papers as a 50th Anniversary edition, the 26240OR represents the kind of dated, purposeful reference that secondary market history consistently rewards. Its combination of precious metal construction, landmark anniversary provenance and the finest in-house chronograph movement Audemars Piguet has ever produced ensures it will be counted among the pivotal Royal Oak references for as long as collectors gather to discuss the canon.
