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

This Seikonaut configuration pairs a warm rosegold case with a stealthy black rubber strap, creating a clean, modern contrast that feels luxurious yet wearable. Designed around a 40mm integrated Nautilus-style case, it’s powered by the Seiko NH72 skeleton movement, which reveals the golden mechanics beneath through a fully open dial layout.

Unlike a traditional Seiko Nautilus open heart that offers just a peek into the movement, this build goes all-in — exposing the entire gear train, balance wheel, and architectural bridges. It’s not just a detail; it’s the whole design.

This setup replaces your typical Seiko dial with a full mechanical display that brings life and depth to the watch — giving it presence and personality with every turn of the wrist.

Compatible with top-tier Seiko mod watches components, this Seikonaut offers perfect proportions, a reliable movement, and a high-impact aesthetic that’s anything but standard. For modders seeking a bold mechanical style with luxury overtones, this is a top-tier choice.
