Seikonaut – Black PVD Skeleton Mod with Rosegold Dial & Blue Strap (40mm)

This 40mm Seikonaut build makes a statement with dynamic color play and open mechanical depth. The black PVD case contrasts sharply with rosegold hands and markers, while the vivid blue strap adds a modern, sporty edge that lifts the entire design.

At the center is the Seiko NH72 skeleton movement, fully exposed and golden beneath the dial — creating a visual experience that outshines a basic Seiko Nautilus open heart layout. Rather than just a partial cutout, this mod offers a fully open dial where the entire movement comes to life.

The warm tones of the dial reflect beautifully against the dark case and golden bridges, while the blue strap ensures this build never fades into the background. Compared to a classic Seiko dial, this configuration feels alive — detailed, moving, and built to engage.

Crafted with premium Seiko mod watches components, this Seikonaut merges refined watchmaking with bold personality, offering both substance and presence in a wearable, everyday package.
