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 Ultra Thin Rose Gold Seikonaut case blends refined aesthetics with groundbreaking engineering to create one of the slimmest Seiko modding cases ever made. Measuring 9.95 mm (closed) and 10.3 mm (open caseback), it offers an exceptionally sleek Nautilus-inspired profile rarely seen in Seiko mods. Designed for NH35, NH36, NH38, NH70, NH71, and NH72 movements, it fits 30.8 mm dials, supporting skeleton, open-heart, and classic Seiko mod configurations.

Crafted for modders seeking a refined, luxury Seiko mod foundation, this rose gold Seikonaut case offers the precision, slim engineering, and durability required to build a truly premium Seiko mod experience.

FAQs

Nomods is based in Oslo, Norway. We offer shipping from our workshop here, or directly from our factory depending on buyers location. Read more about this in our shipping policy!

No chapter ring is needed! Our Petrichor Seiko Modding case as one case and it ready to be built with!

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.

Our Petrichor Seiko Modding Case houses 28.5/29mm dials!
