Description
The 38mm Steel Caseback is a precision-machined replacement caseback for Seiko mod builds on NH35-based cases. If you want a clean, closed finish on the back of your mod — without a display window — this solid stainless steel caseback is exactly what you need. It screws in flush and gives the case a refined, tool-watch look from any angle. Whether you are finishing a new build or replacing a worn or damaged caseback on an existing mod, this part slots in without modification.

Why choose a solid caseback?
A closed steel caseback does more than cover the movement — it completes the aesthetic of a purpose-built sport or tool watch. The flat profile sits flush against the wrist and eliminates the slight protrusion a crystal caseback can introduce. If you are building a compact, everyday-carry mod where wrist comfort and a clean silhouette matter more than showing the rotor, a solid steel back is the correct call. It also offers better long-term sealing compared to a mineral or sapphire display caseback, which can develop micro-gaps over years of use.
