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.
