Questions before you buy

Can't find your answer? Write to us and the team will reply.

What is a Seiko mod?

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.

Are you affiliated with Seiko or any luxury brand?

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.

Does it need a battery?

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.

Which size is right for me?

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.

Will the bracelet fit my wrist?

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.

Can I swim with it?

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.

How long does shipping take?

Shipping is free worldwide with tracking. Your watch is prepared in 2 to 5 days and usually arrives 15 to 25 days after you order. Express shipping (2 to 6 days) is available at checkout.

How do I pay?

All major cards, PayPal, Apple Pay, Google Pay and Shop Pay. Checkout shows every option available in your country, including paying in instalments where offered.

Can I return or exchange it?

Yes. You have 30 days from delivery. Start from the return form or read the refund policy.

What does the warranty cover?

Every watch has a 1-year warranty covering movement failure and any material or assembly defect. Outside warranty, write to info@modhousewatches.com and we'll still help.

How can I track my order?

You get a tracking link by email as soon as your watch ships. Can't find it? Check your spam folder or contact us with your order number.
