Quality takes time.
The Naut Mod Snow White Open Heart takes the minimalist white-dial formula and opens it up — literally. A cutout aperture in the dial exposes the visible NH38 front mechanism in motion, layering horological character onto an otherwise restrained aesthetic. The contrast between the clean white surface and the mechanical complexity visible beneath it is what makes this variant stand apart from the standard Snow White. It is a Seiko Mod that rewards a closer look.
Case: 41 mm stainless steel – integrated-bracelet sports profile
Movement: Seiko NH38 automatic – hacking, hand-winding, ~41 h power reserve, 21,600 bph
Crystal: Sapphire with Super-LumiNova – scratch-resistant, legible in any light
Crown: Screw-down, 5 ATM water resistance – sealed for daily use
Bracelet: Adjustable stainless steel with butterfly safety folding clasp – flush fit, confident lock
Case back: Exhibition window
White dials demand precision in every detail, and the open-heart window adds another dimension: the moving parts of the NH38 become part of the visual design. You do not just wear this watch — you watch it work. Hand-assembled at MedoMods, each piece is checked individually before shipping. An automatic Seiko Mod that combines the calm of a clean white dial with the fascination of exposed mechanics, on an integrated stainless bracelet built to last.
Secure payment
A Seiko mod is a modified watch that uses an authentic Seiko movement, combined with third-party high-quality parts. Most of our watches come in stainless steel with sapphire crystal.
It usually takes 10–12 days from order to delivery. The reason: we build every watch by hand only after you order it. It then goes through quality control, and only after that do we ship it. With Priority Build (an optional extra for €9.99, chosen on the product page) your watch moves to the front of the bench.
Absolutely. Send us an email with your order number and full name after ordering, stating your desired design or that you want to remove the logo. You can also leave a note at checkout, or contact us before ordering.
Yes. Every watch comes with a 2-year warranty from delivery. It covers manufacturing defects and functional problems under normal use. It doesn't cover scratches, damage from opening the watch, or water damage. If your watch is rated 5 ATM, hand-washing and rain are fine. Avoid diving, hot water and showering.
MedoMods is run by AM GbR, based in Leimen near Heidelberg, Germany. Our address and VAT ID are in the legal notice. You pay through Stripe, for example by card, PayPal or Klarna, and your card details never reach us. For deliveries to the UK, USA and Australia, we offer 14-day returns from delivery. We do not charge an additional restocking fee. We issue refunds within 4 calendar days after receiving the return. Every watch comes with a 2-year warranty. You can find our seller ratings on eBay.
We push prices down as much as we can. We believe many comparable watches are overpriced because shops bundle extras (like extra straps) into the price. We let you choose what you want, so you only pay for what you actually need.
Yes. We source from suppliers who sell authentic Seiko movements. The specific movement is listed on each model’s product page. If you suspect that your watch contains the wrong movement or a non-genuine one, contact us with your order number and a description.

„J'avais un doute sur le rendu en vrai. Un détail décisif : le cadran open heart, le style clair et la silhouette Naut.“

„El acabado era mi mayor duda. Me fijé en la silueta Naut, la esfera open heart y el estilo claro. Ahora ya no tengo dudas.“

„Jeg ville valgt denne varianten igjen. Det jeg liker best: Naut-kasseformen, den åpne urskiven og det lyse uttrykket.“
