ROYAL OAK PERPETUAL CALENDAR 26674ST – CELEBRATING LEGENDARY STAINLESS STEEL

Like a timeless monument, this watch projects profound luxury through its 41mm case 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 robustly sporty yet exceptionally poetic. Protected by glareproofed sapphire crystal with a water resistance of 50m, this resilient shell embraces the highly sophisticated Calibre 7138 within, preserving the pioneering spirit of Le Brassus.

HARMONIOUS GRANDE TAPISSERIE DIAL AND PERPETUAL MECHANICS

The soul of this masterpiece resides in its blue dial adorned with the renowned "Grande Tapisserie" pattern, creating a powerfully elegant tone-on-tone presence. The subdials perfectly orchestrate the perpetual calendar indications – including the day, date, month, leap year, week of the year, and an astronomical moon phase – balanced flawlessly across the mechanical landscape. The 18-carat white gold applied hour-markers and Royal Oak hands, treated with high-grade luminescent coating, act as guiding stars to guarantee absolute legibility under the darkest conditions.

CALIBRE 7138 HERITAGE – THE PULSE OF INFINITE PRECISION

Through the glareproofed sapphire caseback, connoisseurs are granted an exclusive view into the breathtaking microscopic architecture of the new-generation selfwinding Calibre 7138. With an impressive thickness of just 4.1mm, this highly complex engine integrates 420 meticulously chamfered and hand-polished components. By optimizing the ergonomics of the perpetual calendar system, the movement delivers a robust 55-hour power reserve. The flawless fusion of legendary steel and complex mechanical art makes this creation an invaluable symbol of modern Haute Horlogerie.
