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.
