Assembling a watch with this case is straightforward for anyone familiar with NH35 movements, with clearances that make the installation process smooth. Once assembled, the square profile sits comfortably on the wrist and offers a distinct visual upgrade from standard circular cases.
This case is perfect for DIY watchmakers and mod enthusiasts looking to build a distinctive square-cased timepiece.
