Description

The GMT Mod Ocean Blue is built for the traveller who wants a second time zone without the complexity of a second watch. The ocean blue ceramic bezel brings a clean, open-water feeling to the dial — lighter and more luminous than navy, with an energy that suits the watch's purpose as a travel companion. At 40 mm on a stainless steel bracelet, it wears across contexts from the airport to the office without demanding explanation.

Movement

The Seiko NH34 automatic movement uses a separately adjustable 24-hour hand for a second time zone.

Case & Crystal

The 40 mm stainless steel case strikes the balance between everyday comfort and wrist authority. Sapphire crystal paired with Super-LumiNova on the dial indices and bezel markers means the two time zones remain legible in any light condition.

Dial & Design

Ocean blue as a bezel colour reads differently from the blueberry variant: it is brighter, fresher, and more immediately cheerful without sacrificing the seriousness that a functional GMT watch demands. The ceramic insert resists the fading and chipping that plague aluminium alternatives over years of wear. The dial layout is clean — hour, minute, GMT hand, and date working in a well-organised space.

On the Wrist

The 40 mm case and ocean blue bezel combination is versatile in a way that heavier GMT watches often are not — it works with a business shirt sleeve or a rolled-up casual cuff equally well. The ceramic bezel holds its colour over time far better than painted or anodised alternatives. A Seiko mod that genuinely earns its function.

FAQ

What is a Seiko mod?

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.

How long will it take to receive my watch?

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.

Can I customize the logo or remove it?

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.

Do you offer a warranty?

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.

Is MedoMods a legitimate shop?

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.

Why are your watches cheaper than those in other shops?

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.

Do you use genuine Seiko movements?

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.

Are the watches hand-built?

Yes — all our watches are built by hand.
