ROYAL OAK SELFWINDING CHRONOGRAPH 26240ST – THE HARMONY OF STAINLESS STEEL AND HERITAGE BLUE

Like a timeless monument radiating a quiet, masculine strength, this watch projects profound luxury through its 41mmcase and integrated bracelet, both crafted entirely from premium stainless steel. The iconic interplay of satin-brushed surfaces and highly polished bevels creates an architectural stance that is robust, commanding, and exceptionally sporty. Protected by glareproofed sapphire crystal with a water resistance of 50m, this resilient metal shell embraces the highly sophisticated Calibre 4401 within, preserving the ultimate luxurious heritage and pioneering spirit of Le Brassus.

LEGENDARY BLEU NUIT NUAGE 50 GRANDE TAPISSERIE DIAL

The soul of this masterpiece resides in its "Bleu Nuit, Nuage 50" dial—a legendary hue deeply rooted in the collection's history since the first Royal Oak in 1972—adorned with the renowned "Grande Tapisserie" pattern. The three chronograph sub-dials share this deep blue tone, creating a powerfully harmonious presence. Breaking this serene landscape are the applied hour-markers and Royal Oak hands, crafted from 18-carat white gold. Generously treated with high-grade luminescent coating, these precious metal elements act as guiding stars to guarantee absolute legibility under any lighting condition, delivering a highly luxurious design language.

CALIBRE 4401 HERITAGE – THE PINNACLE OF FLYBACK CHRONOGRAPHS

Through the glareproofed sapphire caseback, connoisseurs are granted an exclusive view into the breathtaking microscopic architecture of the in-house selfwinding Calibre 4401. Featuring a highly complex Flyback Chronographmechanism that allows the wearer to restart the chronograph instantly without stopping or resetting it first, this movement is a testament to ergonomic superiority. Composed of 381 meticulously hand-finished components, it delivers a robust 70-hour power reserve. This solid stainless steel creation is far more than a time-telling instrument; it is an invaluable symbol of precision and the art of luxurious living.
