Frequently asked questions

Is a Yacht-Master 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?

Not as standard. Standard builds are splash-resistant: fine for rain, hand-washing and everyday wear, but not for swimming, showering or diving. To swim with it, add the Swim-Ready 5 ATM upgrade when you order, and screw the crown down before any water.

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?

Prices show in your currency on each watch. Every build is made to order, in 1 to 2 weeks from order to dispatch, with free worldwide shipping and a 2-year warranty.
