Home / Seiko Aquanaut
Seiko Aquanaut Seiko mods hand-built in Australia: sapphire crystal, 316L stainless cases, premium bracelets and reliable Seiko automatic movements. Every watch is timed, inspected and shipped free, with a 12-month warranty.
We build each Seiko Aquanaut to order using genuine Seiko automatic movements and quality components - the look of a $3,000+ luxury sports watch without the price tag. Browse the collection above or build your own in our watch configurator.
