At 41mm in diameter and 12.4mm in thickness, the case is engineered for daily wear while maintaining the strong wrist presence expected from a Royal Oak chronograph. A screw-locked crown, combined with glareproofed sapphire crystal and sapphire caseback, completes the robust construction and supports a 50-meter water resistance rating.

The standout feature of this reference is its khaki green dial. Finished with the iconic “Grande Tapisserie” pattern, it offers depth and texture that shifts subtly with the light. The dial is paired with khaki green counters, while white gold applied hour-markers and Royal Oak hands feature a luminescent coating for strong legibility in low-light conditions balancing luxury aesthetics with practical readability.
