Seikonaut – Black PVD Skeleton Watch with Silver Dial & Blue Strap (40mm)

This 40mm Seikonaut pairs stealthy black PVD finishing with bright silver dial components and a deep blue rubber strap, delivering a premium mod that’s sporty, sharp, and full of movement.

Powered by the Seiko NH72 skeleton movement, this build exposes the entire mechanical architecture — giving you a bold, openworked display that goes far beyond the partial window of a Seiko Nautilus open heart. You don’t just get a glimpse of the balance wheel — you get the full story.

The polished silver hands and markers stand out crisply against the golden skeletonized movement, offering both readability and visual depth. Compared to a traditional Seiko dial, this configuration feels alive — rotating, ticking, and layered in detail.

The black PVD case is scratch-resistant and understated, while the blue strap adds a pop of contrast that keeps the watch from feeling too aggressive. It’s a balanced, highly wearable entry in the upper tier of Seiko mod watches — combining mechanical expression with confident style.

No it does not! Our 37mm Royal Oak Seiko Modding case arrives as one complete case, and is ready to house a movement straight from the box.

In order to make this Seiko Mod Case as thin as possible, there is limited room in the back of the case. Therefore some custom NH35 rotors do not fit. Pay close attention to the respective rotor. Does it exceed the height of the middle screw? If yes then it may be too thick for this case.

We recommend a 28.5/29mm dial for our 37mm Royal Oak Case. The typical 31.8mm mod dials that many Royal Oak Mod Cases use are too big.
