Quality takes time.
The Yacht Mod Grey is a sport-diver Seiko mod built around a grey dial that threads the line between tool watch and everyday wear. Grey reads as serious without being oppressive — it matches with almost everything, from a wetsuit to a work shirt. The 40 mm case keeps the proportions dialled in for a wide range of wrist sizes, and the bidirectional bezel adds function without making the watch feel like gear. This is the mod for someone who wants a capable, honest automatic that wears seven days a week.
Grey dials have a reputation for being a modder’s colour — subtle enough to disappear under a sleeve, strong enough to hold attention when it matters. The Yacht Mod Grey leans into that logic. The NH35 movement underneath is proven across thousands of builds and services well when the time comes. Hand-assembled by MedoMods, shipped EU-wide with no customs costs — a straightforward way to own a handcrafted automatic without importing from overseas.
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.

„One detail caught my eye in the photos: the grey tone and the sporty Yacht styling. On the wrist, the whole design looks even better balanced.“

„Die Verarbeitung war für mich die entscheidende Frage. Aus der Nähe gefällt mir die Umsetzung: die sportliche Yacht-Optik und der Grauton.“

„Je choisirais de nouveau cette variante. Le détail qui me plaît le plus : le style Yacht sportif et la teinte grise.“
