Our Royal Oak-style Seiko mods are integrated-bracelet sports-luxe watches built around genuine Seiko movements (mostly the NH35 automatic), wearing the octagonal bezel, tapisserie-style dial and seamless integrated bracelet. 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.

Architecture for the wrist. The Seiko Royal Oak mod collection brings the integrated-bracelet sports-luxury silhouette to a reliable Japanese movement. Dials include black, blue, light blue, white, green and skeleton.
Seamless integrated bracelet, sapphire crystal, built to order with free worldwide shipping. Every part is named in the open, and the money goes into the watch. Not a copy. A choice.
Which Seiko Royal Oak mod should you buy?
Short answer: decide on the movement first. The three-hand builds run a genuine Seiko NH35 automatic, the skeleton and open-heart builds run the Seiko NH70 or NH38 automatic, the chronographs run the Seiko VK63 meca-quartz, and the 31mm Lady Royal Oak runs the Seiko VJ24 quartz.
Three-hand automatics
Blue, Black, White and Green are the core dials, and Rose Gold pairs a black dial with a rose gold case and bracelet. They come in 41.5mm or 39mm, and the 39mm case costs more.
Skeleton and chronograph
The Skeleton shows the NH70 through the dial, and the Rose Gold Skeleton uses the NH38 open heart. For a stopwatch, the Panda and Black chronographs run the VK63 meca-quartz: quartz timekeeping with a mechanical chronograph module.
Every build has sapphire crystal, is made to order and quality-checked (automatics are regulated before they ship), and carries a 2-year warranty with free worldwide shipping. Sizes are approximate.
Frequently asked questions
Is a Royal Oak mod a real automatic?
Most are. The three-hand builds run a genuine Seiko NH35 automatic and the skeletons an NH70 or NH38, all self-winding. The chronographs run a Seiko VK63 meca-quartz and the Lady Royal Oak a Seiko VJ24 quartz, and we say so on their pages.
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?
Price depends on the movement and case size: the three-hand builds cost a little more than the skeleton, chronograph and Lady Royal Oak builds, and the 39mm case costs more than the 41.5mm. The Swim-Ready (5 ATM) upgrade is an optional extra. Every product page shows the current price in your local currency. Every build is made to order, in 1 to 2 weeks from order to dispatch, with free worldwide shipping and a 2-year warranty.
What sizes do they come in?
Three-hand and skeleton builds come in 41.5mm or 39mm, and the Lady Royal Oak is 31mm. Sizes are approximate.
