Description

The Naut Mod Snow White Open Heart takes the minimalist white-dial formula and opens it up — literally. A cutout aperture in the dial exposes the NH38 rotor in motion, layering horological character onto an otherwise restrained aesthetic. The contrast between the clean white surface and the mechanical complexity visible beneath it is what makes this variant stand apart from the standard Snow White. It is a Seiko Mod that rewards a closer look.

Open Heart on a White Canvas

White dials demand precision in every detail, and the open-heart window adds another dimension: the moving parts of the NH38 become part of the visual design. You do not just wear this watch — you watch it work. Hand-assembled at MedoMods in Germany, each piece is checked individually before shipping. An automatic Seiko Mod that combines the calm of a clean white dial with the fascination of exposed mechanics, on an integrated stainless bracelet built to last.
