Chronograph functionality introduces a more technical and energetic personality to the Royal Oak 26331ST while preserving the architectural elegance of the original Royal Oak design. The stainless steel case and integrated bracelet feature alternating brushed and polished surfaces that intensify the sharp geometry surrounding the octagonal bezel. On the dial, recessed chronograph counters create additional depth across the Grande Tapisserie pattern without disrupting overall balance and symmetry.

The reference is powered by the selfwinding Calibre 2385 chronograph movement, admired for its slim construction and responsive chronograph operation. Sapphire crystal on both sides reveals refined movement finishing alongside the compact rotor architecture. The 26331ST remains one of the most versatile Royal Oak chronographs, combining practical sports functionality with high horology finishing and unmistakable integrated bracelet design.
