At 42mm, the stainless steel case houses a glareproofed sapphire crystal and caseback, while the crown and pushpieces are rendered in black ceramic with screw-lock security. A case thickness of 14.22mm gives the watch a substantial, purposeful presence on the wrist, and water resistance reaches 100 metres.
The black dial is decorated with Audemars Piguet's signature Méga Tapisserie pattern and features black counters, white Arabic numerals with a luminescent coating, and white gold Royal Oak hands that are likewise treated for low-light legibility. A black inner bezel completes the darkened, cohesive aesthetic that earned this reference its "Vampire" nickname.
The watch is fitted on a black rubber strap, keeping the overall composition unified and sport-forward. Reference 26470ST.OO.A101CR.01 stands as one of the more visually dramatic entries in the Royal Oak Offshore Chronograph lineage.
