Seikonaut – Black Skeleton Seiko Mod with Silver Dial and Gray Strap (40mm)

This 40mm Seikonaut strikes a balance between stealth and sophistication, combining a matte black PVD case, polished silver hands and indexes, and a versatile gray rubber strap. It’s a cool-toned mod designed for daily wear — with just the right amount of mechanical intensity.

At its heart is the Seiko NH72 movement, fully skeletonized and exposed. Unlike standard Seiko dials, this layout removes the top plate entirely, giving you a clear, layered view of the gears and balance wheel in motion. It’s the next step beyond a Seiko Nautilus open heart, offering full mechanical visibility instead of a limited cutout.

The gray strap grounds the watch in neutrality, making the silver details and golden movement shine all the more. Built using top-tier Seiko mod watches components, this setup ensures compatibility, precision, and a sharp modern aesthetic.

Ideal for modders and collectors who want a skeletonized look with everyday wearability and contrast-driven styling.
