Note: This is a pre-order of the case only. Final production may vary slightly from current specifications. The thinnest Seiko mod case on the market is 9.96 mm. While our design targets a slimmer profile, if the final thickness is slightly higher and does not set a new record, this will not qualify for a refund.

The Nomods Two-Tone Seikonaut case brings the refined proportions of luxury integrated-bracelet designs into the Seiko modding world. Measuring just 9.95 mm (closed) and 10.3 mm (open caseback), it delivers an exceptionally slim and balanced Nautilus-inspired profile. Compatible with NH35, NH36, NH38, NH70, NH71, and NH72 movements, it fits 30.8 mm dials for seamless alignment across skeleton, open-heart, and traditional Seiko mod builds.

• Dimensions: 40 mm (10H–4H) × 38 mm (12H–6H)

• Crystal: Sapphire with clear or blue AR coating
• Water Resistance: 50 m

With its contrasting silver and gold finish, this two-tone Seikonaut case stands out as a statement piece for modders seeking both elegance and technical precision in their Seiko Nautilus builds.

In order to make this as thin as possible, there is limited room in the back of the case. Therefore some custom 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.
