Audemars Piguet 15551ST Royal Oak "50th Anniversary" SS Ice Blue Dial

This Audemars Piguet Royal Oak reference 15551ST.ZZ.1356ST.01, released in 2022 to commemorate the 50th anniversary of the Royal Oak, is a refined celebration of one of haute horlogerie’s most enduring icons. The 37 mm stainless steel case, enhanced by a diamond-set bezel, frames the light blue “Grande Tapisserie” dial with luminous white‑gold markers and hands. Beneath the glare‑proofed sapphire crystal and exhibition caseback lies the in‑house self‑winding Calibre 5900, offering a robust 60‑hour power reserve and a matching “50‑years” oscillating weight. With a modest 50 m water resistance, this piece balances elegance with everyday wearability. Its combination of commemorative design, technical excellence, and collector appeal—especially the anniversary oscillating weight and diamond bezel—makes it a standout in modern Royal Oak offerings. The watch’s restrained dimensions and signature octagonal profile ensure it remains both versatile and unmistakably AP. A true milestone piece, it captures the Royal Oak’s heritage while offering a contemporary, celebratory edge. Like New with Audemars Piguet box and Audemars Piguet digital warranty card.
