About Seiko Mods

A Seiko Mod is a bespoke timepiece that we hand-assemble, one watch at a time. Starting from a genuine Seiko base model, our artisans meticulously disassemble, modify, and enhance each component to create a truly unique watch that reflects your personal style and stands apart from off-the-shelf designs  .

Our Dedication to Quality

  • 316L Stainless Steel Cases: Renowned for its strength and corrosion resistance, our cases provide a durable foundation for your watch.

  • Sapphire Crystal: We fit every watch with a scratch-resistant sapphire crystal to ensure lasting clarity and protection for your dial  .

Handcrafted Excellence

Every Aurora Mods watch is assembled by our skilled watchmakers. This hands-on process guarantees not only precision but also that each watch becomes a wearable work of art, reflecting hours of dedicated craftsmanship  .

The Power Within: NH35 Automatic Movement

At the heart of our Seiko Mods lies the NH35 automatic movement, celebrated for its robustness and timekeeping accuracy:

  • Precision: Typically gains or loses just 3–5 seconds per day.

  • Power Reserve: Offers an impressive 41-hour reserve, so your watch keeps ticking even if it’s off your wrist for a day or two  .

Form Meets Function

Aurora Mods Watches are more than instruments for telling time—they are personal statements. With every detail fully customizable, your watch becomes a masterpiece that celebrates individuality and superior engineering  .
