      For people who track two time zones. The Seiko GMT mod collection pairs a genuine dual-time GMT movement with the bezel colourways collectors know — Batman, Bruce Wayne, Root Beer and Sprite.

      Japanese automatic movement, sapphire crystal, built to order with free worldwide shipping. The travel-watch look and function for a fraction of the original. Independent and independent. Not a copy. A choice.

      Frequently asked questions

      Is a GMT mod a real automatic?

      Yes. Each one runs a genuine Seiko NH34 automatic with a true independent GMT hand. 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.
