Audemars Piguet Royal Oak, Ref. 15500ST.OO.1220ST.01 - Blue Dial

The Audemars Piguet Royal Oak reference 15500ST.OO.1220ST.01 is presented here in brand new, unworn condition, representing a significant iteration of a horological icon set for a 2025 release.

This timepiece showcases the distinctive 41mm octagonal case and integrated bracelet, meticulously crafted from robust stainless steel. The iconic "Grande Tapisserie" pattern dial, in a distinguished blue, features white gold applied hour markers and Royal Oak hands with a luminescent coating. A date display is positioned at 3 o'clock. The integrated bracelet is secured by an AP folding clasp, ensuring both comfort and security.

• Movement: Powering this timepiece is the Audemars Piguet Manufacture Calibre 4302, an in-house self-winding movement. Operating at 28,800 vibrations per hour (4 Hz) and offering a substantial 70-hour power reserve, the Calibre 4302 is visible through the glareproofed sapphire crystal case back, revealing its exquisite finishing, including Côtes de Genève, circular graining, and a skeletonized 22K gold oscillating weight.
• Case & Dial: The 41mm stainless steel case features the signature octagonal bezel with eight hexagonal screws. It offers a water resistance of 50 meters (165 feet), suitable for daily wear. The glareproofed sapphire crystal protects the blue "Grande Tapisserie" dial.
• Historical Significance: The Royal Oak 15500ST series, introduced in 2019 as the successor to the 15400ST, holds notable importance within the Audemars Piguet lineage. It marked the introduction of the new 4302 calibre to the core Royal Oak collection, previously seen in the Code 11.59, offering enhanced technical performance and reliability. Furthermore, the dial design was refined, featuring a larger AP logo positioned directly at 12 o'clock, omitting the 'Automatic' text, and repositioning the date window further towards the dial's periphery. These changes subtly yet significantly updated the aesthetic while maintaining the Royal Oak's fundamental design principles.

This immaculate condition Audemars Piguet Royal Oak 15500ST.OO.1220ST.01 from 2025 is a highly sought-after piece, combining avant-garde design with precision engineering. Its robust construction, historical relevance, and pristine state make it a compelling investment piece for discerning collectors and enthusiasts.
