NMK939 Fifty-Eight SKX007/SPRD Watch Case Bundle: Gold Finish
Once considered a "Poor Man's Rolex", Tudor has really come into its own in recent times. This NMK939 Fifty-Eight SKX007/SPRD Watch Case Bundle in Gold Finish pays homage to the eternal crowd favourites BB58, a vintage styled diver complete with details such as an ultra slim low profile bezel, top hat sapphire crystal and option for an Oyster Rivet bracelet. The best part is, everything is pre-assembled, making this the perfect plug-and-play dive case. Check out our Fifty-Eight collection for more part ideas!
Design Update: We've heard your feedback and our NMK939 bracelet now comes with a female solid end link!

Namoki’s BB 58 case and bracelet combo are unmatched. For a beginner or an expert at watch building, the case comes with the sapphire and bezel installed which is beyond valuable. I’ve purchased two of these and highly recommend. You can build similar to a homage style or get creative and. Different dial, hands, and bezel insert. Pro tip, use their 15% off bundle offer and add the case plus bracelet, choose a dial and hands. Worth every penny.
I just recently found Namoki Mods and have already built two watches. Great quality fast shipping.
Overall I am happy with the build and finishing on this case. However, I was not very happy with the bezel action and feel. The bezel action has almost no play but turning it feels mushy and unsatisfying.
The clasp on the bracelet that I ordered was broken but customer service rectified this quickly by sending me another one. Although I am overall pleased with the case look and finishing.
Wanted to build a bright Summer watch.
this bb58 inspired case came with excellent tolerances. everything fit together perfectly. This was my first mod and this case made it super easy.
Turned out better then expected. Love everything about this outfit....keep it it up! Lume love is always fun, you should all have a go.
Options and quality like this are why Namoki is the best in the business!
I am happy to have purchased this case. The quality is here. The bracelet is also of good quality even if it pulls my hairs a little.
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.
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.
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!
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.
Great product!
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

The bracelet as a whole is lovely, with good brushing and finishing all over. The vintage style is also well executed and I hope to see this bracelet design for other cases in the future!

The amount of "Wow!" and "How good is that!" comments I have received because of this watch case and bracelet combo has left me with a massive smile on my face. The quality is incredible for the price and the fitment of the the components into it was a breeze. Bezel action is better than Seiko OEM and I didn't have to adjust anything on it. The screws on the bracelet are a god send as I cannot stand pin and collars. To see it at this price point is fantastic. The only issue I have with this combo is that it makes me not want to wear my other watches! What a problem to have.
The case is fantastic, well machined, finished brilliantly and evenly all over. The dimensions are fantastic also. One thing that I will say is the bezel rotation is very tight and namoki recommend swapping the gaskets to make it a bit smoother. I actually removed the click spring and replaced it with a gasket to create a bi directional rotation.

Bezel tension was a lot lighter on this one. Always wanted a red diver from the 70's. This case is a gem.
Love the case, it fit perfectly on my wrist and it's slimmer!
