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

Green became the defining colour of Audemars Piguet's 50th Anniversary Royal Oak celebrations, and Reference 26240ST.OO.1320ST.04 captures this chromatic milestone in stainless steel — the most democratic and arguably most pure expression of the Royal Oak's enduring character. The forest-green Grande Tapisserie dial is among the most arresting in the collection's history, its depth and saturation evoking the landscapes surrounding the Vallée de Joux where Audemars Piguet has been established since 1875. Against this ground, luminous Royal Oak hands and applied hour markers deliver the sports-luxury legibility that Genta encoded into the original 1972 design.

The chronograph functions are powered by Calibre 4401, Audemars Piguet's landmark integrated column-wheel chronograph movement featuring flyback capability and approximately 70 hours of power reserve — placing it confidently among the finest calibres of its type in contemporary production. The 41 mm octagonal stainless steel case with its transparent sapphire caseback sits on an integrated steel bracelet secured by the AP Folding Clasp, the whole assembly water resistant to 50 metres. The octagonal bezel and screw-down crown are finished in Audemars Piguet's characteristic alternation of satin-brushed and mirror-polished surfaces.

Marked as a 2022 model year and presented with full box and papers, this Anniversary edition occupies a singular position in Royal Oak chronograph history. The steel and forest green combination has proven among the most coveted configurations since its launch, resonating with collectors who appreciate the historical gravity of the 50th Anniversary alongside the enduring wearability of stainless steel. At $66,999, Reference 26240ST.OO.1320ST.04 represents the convergence of milestone relevance, mechanical excellence, and bold chromatic conviction.
