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

This 40mm Seikonaut fuses the stealth of black PVD with the warmth of rosegold in a striking skeleton layout. With polished copper-tone dial details set over the fully open NH72 movement, and paired with a smooth black rubber strap, this build is moody, modern, and unapologetically refined.

The skeletonized dial goes far beyond the peekaboo look of a typical Seiko Nautilus open heart — revealing the entire movement, from gear train to balance wheel. It’s a complete departure from the traditional Seiko dial, offering visible complexity and true mechanical character.

Whether you’re looking to upgrade your daily driver or build something with edge, this Seiko mod watch delivers both presence and polish. The combination of dark tones and gold-accented depth gives it the feel of a boutique Swiss piece — but made with accessible Seiko components that modders trust.

A flawless pick for anyone chasing bold contrast and modern watchmaking aesthetics.
