Daytona Mods

Our daytona-style chronograph seiko mods are racing chronograph watches built around a Seiko VK63 meca-quartz chronograph movement (a hybrid, not a full automatic - we always say so), wearing a tachymeter bezel, three sub-dials and crisp, snappy chronograph pushers. Every one carries a sapphire crystal, a 5 ATM (50m) everyday water rating (splash and rain, not swimming or diving), and a 1-year warranty. Made to order in about 2 to 3 weeks with free worldwide shipping, from A$289. Made to be looked at twice.

      The racing icon, rebuilt the Rosevari way. Panda dials, tachymeter bezels and motorsport proportions — each one made to order and quality-checked before it ships.

      Frequently asked questions

      Is a Daytona mod a real watch?

      Yes. Each one runs a Seiko VK63 meca-quartz chronograph movement (a hybrid, not a full automatic - we always say so). The chronograph module is mechanical while a battery keeps the time - we label it meca-quartz, never automatic.

      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, so allow about 2 to 3 weeks before free worldwide shipping.
