Our Aquanaut-style Seiko mods take the rounded-octagon case and the embossed, grid-textured dial, and build them on a genuine Seiko NH35 automatic. Every one carries a sapphire crystal, 316L marine-grade stainless steel and a 1 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 shape that broke the rule that a steel sports watch has to look serious. The Seiko Aquanaut mod keeps the soft-cornered octagon and the tread-pattern dial, and puts a dependable Japanese automatic underneath it.
Eight colourways, from the quiet ones to the loud ones: Black, Blue, Brown, Red, Tiffany, Rose Cocoa, Rose Gold and Rose Gold Baby Blue. One price across all of them, so the choice is about the colour and nothing else.
Frequently asked questions
Is an Aquanaut mod a real automatic?
Yes. Each one runs a genuine Seiko NH35 automatic: 21,600 beats per hour, hacking seconds, hand-winding and around a 41 hour power reserve. No battery, ever.
Does it come on a strap or a bracelet?
These builds wear the integrated rubber-style strap the shape is known for, so the strap line runs straight out of the case instead of sitting under a lug.
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. It is an original Rosevari build: a genuine Japanese automatic movement in a case and dial style that pays homage to a classic. It is sold openly as a Rosevari custom build, never as the genuine article, and every part is named.
What does it cost and how long does it take?
Prices show in your currency on each watch. Every build is made to order, in 2 to 4 weeks from order to dispatch, with free worldwide shipping and a 1-year warranty.
