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 and a 2-year warranty, and is splash-resistant as standard, with a Swim-Ready upgrade you can add at order time. Made to order, with free worldwide shipping. Made to be looked at twice.

The racing icon, rebuilt the Rosevari way. Panda dials, tachymeter bezels and motorsport proportions. Each one is 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?

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 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.
