The steel case is fitted with a screw-locked crown and carries a water resistance rating of 50 metres, lending everyday practicality to its unmistakable form.
The bezel is set with diamonds, drawing contrast against the steel case and the depth of the black dial. A folding clasp secures the leather strap, completing a configuration that moves comfortably between casual and formal settings.
Reference 77321ST.ZZ.D002CR.01 is a distinct expression within the Royal Oak family — one that retains the architecture that made the line legendary while offering a scale and detail set well suited to a range of wearers.
