Audemars Piguet introduced the 15500ST as the successor to the long-running 15400, and this replica Royal Oak 15500ST in black captures every update that came with that transition. The case dimensions remain at 41mm, but the bezel is thinner, the dial window is larger, and the overall proportions feel more contemporary. The 15500ST.OO.1220ST.03 reference specifically pairs a black Grande Tapisserie dial with a stainless steel case and integrated bracelet, staying true to Gerald Genta’s original octagonal design language from 1972.

Technical Overview

• Case diameter: 41mm
• Case material: stainless steel
• Dial: black Grande Tapisserie with date at 3 o’clock
• Crystal: sapphire with anti-reflective treatment
• Bracelet: integrated stainless steel with AP folding clasp
• Movement: automatic
• Water resistance: 50 meters

The transition from 15400 to 15500 brought Caliber 4302, replacing the older 3120. The newer movement added roughly 70 hours of power reserve compared to the 3120’s 60 hours. Case thickness sits around 10.4mm, marginally thicker than its predecessor but imperceptible on the wrist.

Inside the Movement

Caliber 4302 operates at 28,800 vph with a date complication visible through the window at 3 o’clock. The black dial offers strong contrast against the white gold applied markers and luminous coating on the hands. Within the Royal Oak collection, the black steel 15500 sits as the versatile daily wearer. For a different color approach in the same case, the 15500ST blue dial variant swaps drama for a cooler, more casual tone.

What Sets It Apart

The 15500 is the current-generation Royal Oak Selfwinding in steel, which makes it the most recognizable reference in the lineup today. Black dial on steel bracelet is the combination most associated with the Royal Oak silhouette. This replica Royal Oak 15500ST in black delivers the updated case geometry and movement specs that separate the current generation from everything that came before it.
