Drawing inspiration from the timeless Aquanaut silhouette, the Seiko Mod Aquanaut offers a refined 41 mm timepiece that strikes the ideal balance between quality craftsmanship and everyday accessibility.
Your watch arrives in a minimal black watch case, protected by film and packed to reach you in perfect condition. Inside you'll also find a bracelet adjustment tool, so you can size it to your wrist at home in a couple of minutes.
Your order is assembled with care, a process that typically takes time depending on material availability.
We offer two shipping options:
- Express Shipping 2-6 working days, for a fee.
- Standard Free Shipping 15-25 days.
This is a transparent and honest estimation based on the majority of our orders.

Tap a number on the watch to see what each part is made of.
Wind it once, then let your wrist do the rest. An automatic movement keeps running as long as you wear it.
A watch built around a genuine Seiko movement, with aftermarket parts for the case, dial, hands and bracelet. We choose every combination, so you get a look you won't find on the shelf.
No. ModHouse isn't affiliated with Seiko or any other watch brand. We use genuine Seiko movements because they're reliable and any watchmaker can service them.
Not on automatic models (NH34, NH35, NH36, NH38, NH70, NH72). They wind themselves as you wear them and keep running for about 41 hours off the wrist. If yours stops, wind the crown 20 to 30 turns or simply wear it.
Some chronograph models use Seiko VK mecha-quartz movements, which run on a battery. The movement is listed on every product page.
Most models are 39 to 40 mm. Some are also offered in 36 mm, which suits slimmer wrists or a vintage look. The case size is in the specifications of each watch.
Bracelets adjust from about 14.5 to 22 cm. Every box includes a link removal tool, so you can size it at home in a couple of minutes. Any jeweller can do it too.
Most models are rated 3 ATM: fine for rain and washing your hands, not for swimming or showering. The water resistance of each model is in its specifications.
