Seiko Labs is an independent watchmaking brand that specializes in modifying and enhancing Seiko-based timepieces. While we use genuine Seiko movements in our builds, we are not affiliated with, endorsed by, or sponsored by Seiko Holdings Corporation in any way. Our watches are carefully assembled using a mix of OEM, after-market, custom/bespoke, and specialty parts to create unique, high-quality timepieces that stand apart from standard factory models.

Each watch is a hand-assembled, made-to-order piece, crafted with precision and care. Our modifications and designs bring a fresh perspective to Seiko’s legacy of watchmaking, blending heritage with individuality.

All watches are made to order, ensuring each timepiece meets the highest standards of quality and craftsmanship. Due to our global sourcing of premium parts, the production process requires a minimum of 3 weeks and can take up to 6 weeks in some cases. If a specific component is delayed or needs to be reordered, this may extend the timeline. Every watch is carefully assembled with attention to detail, making the wait well worth it.

We take pride in our global sourcing process, ensuring that each timepiece is crafted with the best materials available. All of our watches feature genuine Seiko movements, guaranteeing reliability and precision. However, the rest of the components—including cases, dials, hands, bezels, and bracelets—are sourced from a mix of OEM, after-market, custom/bespoke, and specialty suppliers.

We partner with trusted manufacturers across Asia, Europe, and the U.S., carefully selecting each part to meet our high-quality standards. Every watch is fitted with a sapphire crystal, the industry standard for premium timepieces, offering superior scratch resistance and durability. This commitment to quality and craftsmanship ensures that each SeikoJust watch is not just a timepiece but a statement of refined watchmaking.

At Seiko Labs, we thrive on creativity and customization. If you have a unique watch idea—no matter how bold or unconventional—don’t hesitate to submit a custom order request. We’re always up for a challenge and will do our absolute best to bring your vision to life.

Simply provide a detailed description of what you're looking for, and if possible, include reference pictures to help us better understand your concept. Once we review your request, we’ll get back to you with design options, available parts, pricing, and estimated turnaround time.

Very rarely do we have to say no, but in cases where certain elements aren’t possible, we’ll work with you to find the closest possible alternative that still delivers the look and feel you want. If you can dream it, we can build it. Let’s create something incredible
