Audemars Piguet Royal Oak Frosted Gold Selfwinding Chronograph White Gold — Blue Tapisserie Dial | Ref. 26331BC.GG.1224BC.02

The Frosted Gold treatment — developed through a collaboration between Audemars Piguet and Florentine goldsmith Carolina Bucci — transformed the Royal Oak's surface language by hammering 18-carat gold with a diamond-tipped tool, producing a hammered, sparkling texture entirely unlike traditional polished or brushed finishing. Reference 26331BC applies this craft technique to an 18-carat white gold Royal Oak Chronograph, creating an effect that catches and scatters light with extraordinary luminosity while honouring Gerald Genta's foundational octagonal architecture.

Measuring 41 mm with a solid caseback, this chronograph is powered by Calibre 4401 — Audemars Piguet's column-wheel flyback chronograph manufacture movement offering a 70-hour power reserve and vertical clutch mechanism for instantaneous start without the hand-jerk associated with horizontal clutch designs. The blue dial presents the Grande Tapisserie guilloché pattern in characteristic Royal Oak fashion, with the chronograph's subdials integrated cleanly into the overall layout. The white gold bezel wears the same frosted texture as the case, while the integrated white gold bracelet — also frost-treated — carries the technique across the entire form. An AP folding clasp secures the bracelet.

Produced between 2017 and 2021 and presented here with box and papers, this reference occupies a distinctly collectible niche: it merges the Royal Oak Chronograph's sports watch pedigree with an haute joaillerie surface technique, making it equally at home at an art gala or a racing circuit. A definitive piece for collectors who prize technical refinement and artisanal distinction equally.
