Full Set | International Audemars Piguet Warranty Until April 2030The Royal Oak overturned the downwards trend in 1972 during a period of existential crisis for the watch industry due to the boom of cheap quartz watches made in Asia. Audemars Piguet needed a bold, solid stainless steel luxury sports watch, and they entrusted the mission to renowned designer Gerald Genta. Inspired by a deep-sea diving helmet, he created an octagonal bezel with visible mounting screws, a large 39mm case with an integrated bracelet, and a futuristic design that redefined watchmaking in the seventies.The first model released was the reference 5402, known today as the "Royal Oak A Series," featuring the thin automatic calibre 2121 movement, which is still in production today. Treating steel with the same meticulous finishing as gold, Audemars Piguet set a new benchmark in luxury, with a retail price significantly higher than similar Rolex sports watches of that era.The reference Royal Oak Selfwinding 15550ST.OO.1356ST.07 features a 37mm stainless steel case with the signature eight silver screws on the iconic bezel. This watch has a stunning grey dial engraved with the "Grande Tapisserie" pattern. White gold applied hour markers and Royal Oak hands with luminescent coating enhance readability, while the date window is positioned at 3 o’clock and Audemars Piguet in white gold at 12 o’clock.Beneath the dial lies the selfwinding calibre 5900 movement, visible through the glareproofed sapphire crystal case-back. This movement offers hours, minutes, center seconds, and a date function, with an impressive power reserve of approximately 60 hours.The Royal Oak is fitted with a full stainless steel bracelet, secured by an AP folding clasp, providing both elegance and durability for all your favorite activities.This remarkable Audemars Piguet Royal Oak Selfwinding 37 is in Mint Condition and comes with the original Invoice, Audemars Piguet Warranty Card and Box. Furthermore, the watch still has Worldwide Audemars Piguet Warranty until April 2030.
