Audemars Piguet Royal Oak Chronograph White Gold — Purple Grande Tapisserie Dial | Ref. 26240BC.OO.1320BC.01

Gerald Genta's 1972 masterpiece reaches a chromatic pinnacle in this white gold Royal Oak Chronograph, where a deep amethyst purple dial transforms one of horology's most celebrated architectures into something genuinely arresting. The Grande Tapisserie pattern — that hand-guillochéd chequerboard that has defined Royal Oak dials for over five decades — gains new dimension under the purple lacquer, shifting from violet to plum depending on the angle of light.

Powering the 41 mm octagonal case is Calibre 4401, Audemars Piguet's in-house integrated column-wheel flyback chronograph movement. Beating at 4 Hz with a 70-hour power reserve, Cal. 4401 is widely regarded as one of the finest integrated chronograph calibres in production, featuring a vertical clutch, silicon escapement, and a beautifully finished movement visible through the transparent sapphire caseback. The white gold case is complemented by a matching white gold bracelet with the iconic AP integrated link design, secured by a screw-locked crown for 50 metres of water resistance.

Purple-dial Royal Oaks occupy a coveted position among collectors, offering immediate visual impact alongside the provenance of AP's most storied reference. Complete with box and papers, this piece represents an exceptional confluence of Genta's geometric genius, manufacture movement excellence, and precious-metal extravagance. An investment-grade trophy for the discerning Royal Oak enthusiast.
