Built around a 42 x 54mm stainless steel case, the Royal Oak Offshore 26170ST pairs the model's signature architecture with a diamond bezel and a striking black dial. Arabic numerals mark the hours beneath a sapphire crystal, while the stainless steel bracelet fastens with a fold clasp — carrying the design's assertive proportions from the case all the way to the wrist.
Inside, the automatic caliber 3126/3840 powers the watch with a 55-hour power reserve and runs on 59 jewels. The case is water resistant to 10 ATM, adding a layer of practicality to its bold aesthetic presence.
This example is available as a pre-owned piece and is offered without box or papers. Reference 26170ST represents one of the more visually distinctive configurations within the Royal Oak Offshore family, combining the steel construction with the added character of diamond detailing.
