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

This 40mm Seikonaut mod combines rich color contrast with mechanical visibility. Featuring a matte black PVD case, rosegold dial accents, and a vibrant blue rubber strap, this build stands out with its balanced mix of luxury and edge.

Powered by the Seiko NH72 skeleton movement, the fully openworked dial reveals the inner architecture in a way that puts a typical Seiko Nautilus open heart to shame. Instead of a small window, the entire dial surface is carved away — exposing the motion of the gear train and golden bridges.

The rosegold hands and indexes add warmth against the dark movement and case, while the bold blue strap adds a splash of color that transforms the watch from stealth to statement.

As with all premium Seiko mod watches, this piece uses top-tier components and eliminates the limitations of a standard Seiko dial, offering something more dynamic, detailed, and design-forward.

If you are having a hard time removing the screws from the bracelet, take the case and bracelet under some warm soapy water and wiggle each link back and forth. This will clean out residue from production which makes the screws easier to remove and improve the bracelet quality over all

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.
