Description

The Aqua Mod Black is MedoMods' everyday diver: a 41 mm sport watch built on the Seiko NH35 automatic, with a full complement of dive-watch DNA — sapphire crystal, Super-LumiNova, screw-down crown, and an exhibition case back so you can watch the movement work. It is not trying to be exotic. It is trying to be the watch you actually reach for every morning, confident it will handle whatever the day delivers without asking for special treatment.

Movement

The Seiko NH35 inside this Aqua Mod offers hacking seconds, hand-winding and approximately 41 hours of power reserve. It hacks — meaning the seconds hand stops when you pull the crown, enabling precise time-setting — and it winds by hand if you want to top up the power reserve without waiting for the rotor to do it. Approximately 41 hours of power reserve means the watch survives a full weekend off the wrist. The exhibition case back lets you observe the oscillating rotor and the balance wheel ticking away behind sapphire crystal.

Case & Crystal

At 41 mm the stainless steel case is modern in proportion — large enough to read clearly without the bloat of an oversized sport watch. The screw-down crown delivers 5 ATM water resistance: fine for hand-washing, cooking, rain, and day-to-day activities. The sapphire crystal combines scratch resistance with Super-LumiNova application across the dial, so the watch reads clearly whether you are under office LEDs or checking the time in a darkened cinema. No mineral glass here — sapphire is genuinely more scratch-resistant, and it shows after a year of daily wear.

Dial & Design

The black dial is direct: bold applied indices, contrasting hands, and a clean layout that prioritises legibility over decoration. Super-LumiNova charges quickly under light and releases a long, bright glow in darkness — important for a diver-style watch that is meant to be readable in all conditions. The rubber strap keeps the sport character consistent, and the butterfly safety clasp means the watch stays on your wrist even during more active moments.

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.
