What Are Seiko Mods?
Seiko mods are custom-built watches made by modifying genuine Seiko timepieces with aftermarket or original parts. Enthusiasts swap dials, bezels, hands, cases, and movements to create completely unique designs — often mimicking luxury styles or expressing personal taste. The result is a fully personalized watch that costs a fraction of a Rolex or Omega.
- Fully customizable — dials, bezels, hands, cases
- Modded by hand or pro builders
- More affordable than luxury watches
- Built on trusted Seiko movements like the NH35
- Endless design potential — from homages to minimalist builds
