Small Explorer?

This was another test case for me. I wanted something a bit dressier, and not bulky. Other than the bracelet, this is all Namoki--case, dial, hands, and chapter ring. I'm having some issues with the caseback gasket, but I'm sure I will be able to resolve them. I think this is a great-looking case for a host of different builds where you don't want a "dive watch".

A great case for aviation builds.

I got this case bundle just to test out for myself how it is to build with. This is a very easy case to put together into a finished project. So long as you remember SRPE crystal and chapter ring, and not SRPD, everything fits and there isn't a lot extra that the assembler needs to do.

Hilariously fun case

This excellent Namoki case was a build on a whim. I really like how it turned out. Beautiful, perfectly machined, quality parts as always.

Question About Crown

Is this an SKX crown? Will the case fit a standard SRPE crown?

This case need an skx chapter ring or an srpe chapter ring? Thanks
