Quality takes time.
The Naut Mod Chocolate Open Heart in Rose Gold is the most visually complex piece in the Naut Mod line. A warm chocolate dial with a cut-out at 6 o’clock exposes the oscillating balance wheel of the Seiko NH38 — not a display case back trick, but a true open-heart aperture cut directly into the dial. Rose gold accents on the hands and indices pull the warm tones together into something that feels genuinely considered. The integrated 316L stainless steel bracelet follows the Naut Mod’s Nautilus-inspired silhouette: case and bracelet flow as a single piece rather than two parts bolted together.
An open-heart dial does two things at once: it tells the time and shows the mechanism doing it. The NH38 runs without a date wheel, so the balance wheel sits centred under the aperture rather than offset. On a chocolate dial with rose gold detailing, the result is warm, mechanical, and hard to look away from. Every Naut Mod Chocolate Open Heart is hand-assembled by MedoMods, tested before shipping, and delivered from within the EU — no import duties, no customs delays.
If you want a Seiko Mod that rewards a second look, this is the one.
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.
Yes — all our watches are built by hand.

„Un détail ressort dès les photos : le cadran open heart, la finition or rose, la teinte chocolat et la silhouette Naut. Au poignet, l'ensemble est encore plus harmonieux.“

„La revisé de cerca antes de decidir quedármela. Mi detalle favorito sigue siendo la silueta Naut, la esfera open heart, el acabado en oro rosa y el tono chocolate.“

„Det som gjør denne varianten spesiell for meg: Naut-kasseformen, roségull-finishen og sjokoladefargen. Klokken er behagelig å ha på.“
