    I recently purchased a watch from Medomods and couldn’t be happier with the experience. The craftsmanship and attention to detail are outstanding—the watch looks even better in person than in the photos. You can really tell that a lot of care goes into their products. Shipping was smooth and faster than expected, and the packaging was secure and premium. Customer service was also very responsive and helpful when I had a quick question before ordering. Overall, I highly recommend Medomods if you’re looking for a unique, high-quality timepiece. I’ll definitely be coming back for another one!

FAQ

Frequently asked questions

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?
When you place an order, your watch is hand-assembled, regulated and inspected after purchase. Total delivery usually takes 12–15 days. With Priority Build (€9.99) your watch moves to the front of the bench — this does not promise an earlier delivery date.
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?
Every watch from our workshop comes with a free 2-year warranty covering manufacturing defects and operating problems under normal use. Warranty does not cover scratches, damage from opening the watch, or water damage. At 5 ATM, hand-washing, rain and short swims are fine — avoid diving, hot water and showering.
