I ordered this case with bracelet for my Tudor 58 look-alike watch. A very nicely finished watchcase with a pleasantly heavier weight. The bracelet also feels sturdy and has little play in the links.
The bezel is pre-assembled, but in my case it can only be turned with a lot of force. Not the pleasant click action you sometimes see in reviews.
The order was processed correctly and quickly. as well as packaging and shipping.

Black Bay for sure

Comes close to the BB feel. Maybe a little less refined, but great to get into the ballpark. Bezel action is nice!

I modded my dream watch

I am new to modding and i stumbled upon the NMK939, and i knew right then that i have to build my first watch with the BB58 as my inspiration. I got the case bundle and the NH35 mov't from here and such awesome quality and great service by Namoki! Thank you! Will purchase here again.

Awesome quality!

Finally was able to make my own Namoki BB58 mod! Pristine parts! Missed that it did not come with a caseback, luckily, I have an extra one from another mod project!

Namoki is always a go-to when it comes to my mod projects!
