The Audemars Piguet Royal Oak Chronograph 26331BC.GG.1224BC.01 is a distinctive limited-edition timepiece that combines the iconic Royal Oak design with the maison’s celebrated Frosted Gold technique. Limited to just 200 pieces, this exceptional model features an 18kt white gold case and integrated bracelet finished using an ancient gold-hammering technique developed for contemporary watchmaking in collaboration with Florentine jewelry designer Carolina Bucci. 

The 41mm frosted white gold case frames a rich plum-purple dial adorned with Audemars Piguet’s signature Grande Tapisserie pattern. Silver-toned chronograph counters provide a striking contrast against the purple background, while applied white gold hour markers and Royal Oak hands with luminescent coating ensure excellent legibility. The dial features a tricompax chronograph layout, with a 30-minute counter at three o’clock, a 60-second counter at nine o’clock, and a 12-hour counter at six o’clock. A date aperture sits between four and five o’clock, while the inner tachymeter scale adds functionality to the chronograph display. The octagonal white gold bezel, secured by the Royal Oak’s signature exposed screws, complements the shimmering frosted finish and distinctive dial color.

Completing the watch is an integrated 18kt white gold Royal Oak bracelet featuring the characteristic five-link construction and the same frosted texture found throughout the case. The intricate hammered finish scatters light across the bracelet’s surfaces, creating a subtle, diamond-like sparkle that distinguishes it from conventional polished or brushed gold. Designed to flow seamlessly from the case, the bracelet offers a refined and cohesive appearance, secured by an Audemars Piguet folding clasp. The buckle retains its factory stickers, as noted for this particular timepiece.

Powering the Royal Oak Chronograph is the self-winding Audemars Piguet Calibre 2385, an integrated chronograph movement based on the renowned Frédéric Piguet 1185 architecture. Comprising 304 components and 37 jewels, the movement operates at a frequency of 21,600 vibrations per hour (3 Hz) and provides a power reserve of approximately 40 hours. Its column-wheel chronograph mechanism enables precise timing functions, controlled through the pushers positioned on the side of the case. The solid case back preserves the watch’s traditional exterior aesthetic, while the screw-down crown and robust case construction provide water resistance to 50 meters, making it suitable for everyday wear with appropriate care.

The Audemars Piguet Royal Oak Chronograph 26331BC.GG.1224BC.01 stands out as a compelling expression of the manufacture’s technical heritage and artistic innovation. Its limited production of 200 pieces, frosted white gold construction, and richly colored purple Grande Tapisserie dial create a memorable combination of rarity and visual distinction.
