f you’re into watchmaking or simply looking for a timepiece with a unique style, chances are you’ve already heard of Seiko Mods.
At Modus Seiko, it’s more than just assembling parts. It’s about passion, craftsmanship, and the desire to create watches that truly reflect who you are.
What Is a Seiko Mod?
A Seiko Mod (short for modification) is a watch built around a genuine Seiko automatic movement, enhanced with custom components such as dials, hands, cases, bezels, straps, and crystals.
The goal is simple: to create a personalized, one-of-a-kind watch while maintaining the renowned reliability of Seiko calibers.
Why Choose a Seiko Mod?
1. A Unique Watch
Each Seiko Mod is designed as a piece of its own. You’re not wearing a watch seen everywhere — you’re wearing a timepiece crafted with intention, taste, and personality.
2. Reliability & Performance
We exclusively use new and authentic Seiko movements, such as the NH35 and NH36 calibers, known worldwide for their durability, accuracy, and longevity.
3. Premium Components
All other parts are carefully selected: 316L stainless steel cases, scratch-resistant sapphire crystals, genuine leather or FKM rubber straps. Every detail is chosen for both durability and aesthetics.
4. Endless Personalization
Minimalist, sporty, vintage, bold… A Seiko Mod can take on any style, becoming a true extension of your identity.
