      Architecture for the wrist. The Seiko Royal Oak mod collection brings the integrated-bracelet sports-luxury silhouette to a reliable Japanese automatic movement — black, blue and light-blue dials.

      Seamless integrated bracelet, sapphire crystal, built to order with free Australian shipping. Every part is named in the open, and the money goes into the watch. Not a copy. A choice.

      Frequently asked questions

      Is a Royal Oak mod a real automatic?

      Yes. Each one runs a genuine Seiko NH35 automatic. It is fully mechanical and self-winding, powered by the motion of your wrist.

      Can I swim or dive with it?

      No. Every Rosevari watch is rated 5 ATM (50m): fine for splashes, rain and everyday wear, but not for swimming, showering or diving. The look is a style tribute, not a dive rating.

      Is this an original watch?

      Yes. Every watch is an original Rosevari build: a genuine Japanese automatic movement in a case and dial style that pays homage to the classics. Every watch is sold openly as a Rosevari custom build, never as the genuine article, and we disclose every part we use.

      How much does it cost and how long does it take?

      Builds start from A$289 and are made to order, with free worldwide shipping.
