Perpetual Calendar Openworked Titanium & BMG 41MM

ROYAL OAK PERPETUAL CALENDAR OPENWORKED 26685XT – A LEAP IN ARCHITECTURE AND MATERIAL

Like a gateway bridging the present and the future, this highly advanced timepiece shines with an incredibly slim 41mmprofile. The groundbreaking combination of an ultra-light Titanium case middle and a BMG (Bulk Metallic Glass) bezel creates a remarkably robust architecture. BMG—an amorphous metal alloy known for its extreme scratch resistance and mirror-like liquid sheen—contrasts perfectly with the satin-brushed titanium surfaces. With a slender thickness of just 9.5mm and 50m of water resistance, this exceptional shell securely houses a mechanical powerhouse, embodying the relentless pioneering spirit of Le Brassus.

SAPPHIRE OPENWORKED DIAL AND INTRICATE REFINEMENT

The soul of this masterpiece resides in its incredibly detailed Sapphire Openworked dial, revealing the hypnotic dance of the continuous perpetual calendar mechanism. The dial layout is meticulously calculated, featuring matching subdials with a smoked external zone that adds striking visual depth and a floating effect. The presence of 18-carat pink goldapplied hour-markers and Royal Oak hands, both generously treated with luminescent material, not only provides a luxurious contrast but also ensures perfect legibility even in darkness—defying the common readability issues of skeletonized watches.

NEW-GENERATION CALIBRE 7139 AND THE INTEGRATED TITANIUM & BMG BRACELET

Through the sapphire caseback, enthusiasts are granted an unobstructed view of the powerful, new-generation selfwinding Calibre 7139. Composed of 420 micro-components and measuring a mere 4.1mm thick, the movement delivers a steady 55-hour power reserve. The brilliance extends to the iconic integrated bracelet, which combines sturdy Titanium links with mirror-polished BMG studs. This creation is far more than a complex timekeeping instrument; it is a genuine contemporary treasure for collectors who desire the absolute pinnacle of mechanics and materials.
