      FAQs

      The Nautilus Mod uses a genuine Seiko NH35 or NH70 automatic movement depending on variant, featuring 24 jewels, hacking, and hand-winding capability.

      The Seikonaut features Nomods' ultra-thin case design at 9.95mm thickness. The case diameter and lug-to-lug measurements are listed on each product page.

      Nomods developed the thinnest Nautilus-style Seiko modding case available at 9.95mm. The curved caseback allows the case to sit lower on the wrist for improved comfort.
