The Audemars Piguet Royal Oak Selfwinding reference 15510ST.OO.1320ST.09 is a 41mm luxury sports watch featuring a stainless steel case and the collection’s iconic octagonal bezel secured by eight hexagonal screws. This model is distinguished by its khaki green Grande Tapisserie dial, which includes white gold applied hour markers and Royal Oak hands treated with a luminescent coating for enhanced legibility. The watch is powered by the in-house Calibre 4302 self-winding movement, visible through a sapphire crystal caseback, offering a power reserve of approximately 70 hours. The case measures 10.5mm in thickness and is integrated with a stainless steel bracelet featuring an AP folding clasp.
In terms of complications, this timepiece focuses on essential functions, providing hours, minutes, and central seconds alongside a date window located at the 3 o’clock position. The screw-locked crown contributes to its water resistance of 50 meters, making it suitable for light splashes and everyday wear. Its design represents an ergonomic evolution of the Royal Oak line, featuring slightly wider bevels on the case and a more integrated bracelet for improved comfort on the wrist.
General reviews for the 15510ST highlight the captivating sunburst effect of the green dial, which transitions in shade depending on the lighting. The Calibre 4302 is frequently praised for its robust architecture and significant upgrade in power reserve compared to its predecessor. Enthusiasts and collectors often commend the watch for maintaining its classic heritage while introducing a modern color palette, though its high market demand and limited retail availability are common points of discussion. The finishing of the bracelet, which is known to require extensive hand-decoration, remains a hallmark of its high craft quality.
