Audemars Piguet Royal Oak 26586IP.OO.1240IP.01 Perpetual Calendar 'Ultra-Thin' Platinum Titanium Blue Dial

The Audemars Piguet Royal Oak 26586IP.OO.1240IP.01 is a groundbreaking timepiece that redefines ultra-thin haute horology, featuring the world’s thinnest automatic perpetual calendar at the time of its release. Housed in a sleek 41mm case made of titanium with a polished platinum bezel and center links, this watch balances lightweight wearability with the prestige of precious metals. At just 6.3mm thick, it showcases Audemars Piguet’s relentless innovation in pushing technical boundaries without compromising on design.

The sunburst blue dial, adorned with a subtle satin finish rather than the traditional “Tapisserie” pattern, reflects a modern and minimalist aesthetic. The layout of the perpetual calendar functions—day, date, month, leap year, and moon phase—is clear and symmetrical, enhanced by white gold applied hour markers and hands. Powered by the revolutionary Caliber 5133, which is only 2.89mm thick, this timepiece is a marvel of engineering and watchmaking finesse. The Royal Oak 26586IP is more than a watch—it’s a statement of technical mastery and refined modernity, produced in extremely limited numbers for true connoisseurs.
