Audemars Piguet Royal Oak Jumbo Extra-Thin 50th Anniversary 39 Blue Dial Steel 16202ST.OO.1240ST.01

Audemars Piguet Royal Oak Jumbo Extra-Thin 50th Anniversary 39 Blue Dial Steel 16202ST.OO.1240ST.01 The Audemars Piguet Royal Oak 16202ST.OO.1240ST.01 represents the most significant evolution of the “Jumbo” since the original 5402 was released in 1972. Launched in 2022 to celebrate the 50th anniversary of the Royal Oak, this reference replaced the long-standing 15202. While it maintains the iconic 39 mm proportions and the legendary “Bleu Nuit, Nuage 50” (Night Blue, Cloud 50) dial, it features an entirely new in-house movement. This specific reference is a collector’s prize because it features a dedicated “50 Years” anniversary rotor, which was only fitted to watches produced during the 2022 calendar year. The case is crafted from brushed and polished Stainless Steel and maintains the “Jumbo” ultra-thin profile at just 8.1 mm thick. The dial utilizes the “Petite Tapisserie” pattern—the smallest and most traditional version of AP’s signature guilloché—with the AP logo positioned at 6 o’clock, staying true to the vintage aesthetic of the original 1972 “A-Series” models. The watch is integrated into the world-famous Royal Oak bracelet, which underwent a slight ergonomic refinement in this generation to improve the taper and comfort on the wrist. Key Features Model Name Royal Oak Jumbo Extra-Thin (50th Anniv.) Reference Number 16202ST.OO.1240ST.01 Case Material Stainless Steel Dimensions 39 mm (8.1 mm thick) Water Resistance 50 metres (165 feet) Dial Bleu Nuit, Nuage 50 “Petite Tapisserie” Crystal Glareproofed Sapphire (Front and Back) Movement Type Self-winding (Automatic) Power Reserve Approx. 55 hours Caliber Manufacture Calibre 7121 Anniversary Feature “50 Years” logo on oscillating weight Date Function Quick-set Date Components 268 parts Bracelet Stainless Steel with AP Folding Clasp The “Bleu Nuit, Nuage 50” Dial is a masterclass in color preservation. The Original Blue: To achieve the exact shade of the 1972 original, AP uses a PVD (Physical Vapour Deposition) process. This ensures the color is more stable and uniform than the galvanic baths used in the 20th century. Refined Hands and Markers: The white gold markers are slightly wider, and the lume sections are larger than previous generations, improving nighttime legibility without sacrificing the slim “Jumbo” look. Proportional Perfection: The “Jumbo” name is ironic today, as 39 mm is considered a sweet spot for modern collectors. Its 8.1 mm thickness allows it to slide effortlessly under any shirt cuff. The movement is the Manufacture Calibre 7121, replacing the legendary Calibre 2121. 55-Hour Power Reserve: A significant jump from the 40 hours of the previous generation, thanks to a larger mainspring barrel. Quick-set Date: For the first time in Jumbo history, owners can change the date via the crown without having to rotate the hands 24 hours—a massive quality-of-life upgrade.
