This replica Royal Oak 26331ST in blue pairs the steel chronograph case with the dial color that outsells every other option in the Royal Oak catalog. The 26331ST.OO.1220ST.01 is a 41mm stainless steel chronograph with a blue Grande Tapisserie dial, silver-toned subdials, and the integrated bracelet that Gerald Genta drew in 1972. Blue dials on the Royal Oak have always carried a particular magnetism because the Tapisserie texture interacts with light differently at every angle, creating depth that flat-color dials cannot produce.

The 26331ST uses the same case construction as the rose gold 26331OR, but in steel the watch sits lighter on the wrist and the blue dial reads cooler without warm-toned reflections from the case.

Caliber Breakdown

Inside the 26331 sits an integrated automatic chronograph caliber operating at 28,800 vph. The column-wheel mechanism controls the start, stop, and reset functions of the chronograph, offering a smoother pusher feel than cam-operated alternatives. Two subdials handle running seconds at 6 o’clock and 30-minute elapsed time at 12 o’clock. Audemars Piguet finishes the rotor and bridges with circular graining visible through the sapphire caseback. Stacking this against the 15500ST blue on rubber shows the difference between a chronograph and time-only approach to the same dial color. The full Royal Oak collection covers both configurations and more.

How It Compares

Within the 26331 family, the blue steel version is the volume leader. It outsells both the black dial and the panda configuration because blue-on-steel hits the intersection of sport and everyday wearability. The silver subdials add just enough contrast to make the chronograph registers readable without fragmenting the dial layout. Compared to the rose gold 26331OR, this steel version weighs less and pairs with a broader wardrobe. This replica Royal Oak 26331ST in blue is the chronograph reference that most buyers encounter first and come back to last.
