Iconic Design. Sporty Elegance. Exceptional Craftsmanship.

The Audemars Piguet Royal Oak Chronograph 26331ST.OO.1220ST.01 is a powerful expression of luxury sports watchmaking. Instantly recognizable by its iconic octagonal bezel secured with hexagonal screws, this 41 mm timepiece is crafted from high-grade stainless steel, offering both durability and refined aesthetics.

Its “Grande Tapisserie” blue dial, a hallmark of the Royal Oak collection, features three silver-toned subdials at 3, 6, and 9 o’clock, offering chronograph functionality with precision. The applied white gold hour markers and Royal Oak hands are coated with luminescent material, ensuring optimal legibility in low light. A discreet date window is placed between 4 and 5 o’clock.

At the heart of the watch is the self-winding Caliber 2385, a high-performance movement delivering a power reserve of approximately 40 hours. It drives the chronograph, small seconds, and date functions with excellent reliability and smooth operation.

Fitted with an integrated stainless steel bracelet featuring the signature AP folding clasp, the watch sits comfortably and securely on the wrist. The sapphire crystal caseback allows a view of the finely finished movement, demonstrating Audemars Piguet’s renowned attention to detail.

Combining timeless design, mechanical mastery, and sporty sophistication, the Royal Oak Chronograph is a must-have for collectors and enthusiasts of high horology.
