Frequently asked questions
What Is It?
A Seiko Mod is a custom built watch that uses a Seiko movement most commonly the NH35, NH36, or NH34 combined with aftermarket/custom components.
Typically, the builder changes parts such as:
- Dial custom design
- Hands different style/finish
- Case often inspired by luxury watch designs
- Bezel
- Bracelet/strap
- Crystal often sapphire
- Movement genuine Seiko NH-series automatic movement
The important distinction
A Seiko Mod isn't a watch made by Seiko. The movement may be genuine Seiko/NH-series, while the rest of the watch is assembled from third party components.
For example, a watch could contain a genuine Seiko NH35 automatic movement, but have a third-party case, dial, hands, bracelet and crystal.
That's essentially what makes it a "mod": you're modifying/customising the watch rather than buying a complete factory Seiko model.
In simple terms:
Seiko Mod = Seiko automatic movement + aftermarket/custom watch components, assembled into a customised watch.
Is It Genuine?
Yes, Seiko sells their movements to third parties, independent watchmakers, and microbrands. We Pair this with aftermarket parts inspired by iconic models.
