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!
