Namoki 939 Fifty-Eight

First Namoki build and I couldn’t be more pleased. A very nice looking watch and works very nicely with an NH35a I already had.

Case for NH34

Great product!

Awesome case

The dimensions of this case made it ideal for the mil-spec inspired look that was the end goal for this build. Bezel action is solid, crown action is fantastic with a good screwdown function and the domed crystal helps give it that vintage mil-sub vibe also. 11/10
