Second time was the charm

I ordered an NMK941 case for an Explorer II build and it simply wouldn’t accept a movement or dial. I believe the problem was the crown tube was installed incorrectly. I ordered another and it worked great. This is really the first bad experience I’ve had with NamokiMODS. After building about 8 watches with their parts it’s generally a good experience.


Excellent finish on this case!
