Audemars Piguet Royal Oak 26586BC.OO.1240.BC.99 Perpetual Calendar Ultra-Thin “Luminary” White Gold Light Blue Limited Edition of 25

The Audemars Piguet Royal Oak 26586BC.OO.1240.BC.99 “Luminary” represents a new pinnacle of technical mastery and refined aesthetics within the iconic Royal Oak lineage. This highly exclusive limited edition, this groundbreaking perpetual calendar is housed in a 41mm case crafted from 18k white gold, showcasing the impeccable satin brushing and mirror-polished bevels that define the Royal Oak design.

At just 6.2mm thick, the case houses the revolutionary Caliber 5133—the world’s thinnest automatic perpetual calendar movement when it debuted—visible through the sapphire caseback. This ultra-thin architecture is the result of a movement that merges the base and perpetual calendar mechanisms into a single plane, rather than stacking them, achieving breathtaking slimness without sacrificing mechanical complexity. The movement provides an impressive 40-hour power reserve and beats at 19,800 vibrations per hour, embodying Audemars Piguet's tradition of innovation.

The light blue sunburst dial radiates a soft brilliance, offering a modern, airy reinterpretation of the Royal Oak aesthetic. The subdials, indicating the day, date, month, leap year, and moon phase, are harmoniously arranged to ensure maximum legibility and balance. White gold applied hour markers and Royal Oak hands with luminescent coating further enhance its elegant, contemporary appearance.

Paired with a matching 18k white gold integrated bracelet, the 26586BC.OO.1240.BC.99 “Luminary” delivers a seamless fusion of ultra-thin engineering and high-end watchmaking art. Only a select few examples will be produced, making this reference not only a technical marvel but also a highly coveted collector’s piece in the history of the Royal Oak.

The Audemars Piguet Royal Oak Perpetual Calendar Ultra-Thin “Luminary” is the ultimate expression of finesse and innovation, setting a new benchmark for ultra-complicated sports watches.
