Automatic - 41.5mm - Steel caseback

Build your own Royal Oak–style custom watch with the MedoMods Seiko Mod Configurator. Choose your dial, case finish and integrated bracelet to design a bold octagonal-bezel statement piece — powered by the genuine Seiko NH35 automatic movement.

Crafted from durable 316L stainless steel, the case feels as premium as it looks.

The integrated bracelet sits comfortably on the wrist for a secure, seamless fit. Non-chronograph versions are powered by a genuine Seiko NH35 automatic movement for reliable everyday wear.

Chronograph variants use the Seiko VK63 quartz movement for crisp timing performance with a sleek, sporty feel.

Independently built custom Seiko mod using a genuine Seiko movement and third-party aftermarket parts.
