Perfect and beautiful kit

First DIY kit for me. High quality watch parts and first class packaging. More than happy. Namoki rocks at each level. Took me 2 hours to build this gorgeous watch. Lots of fun and satisfaction. Thanks a lot Namoki team.

Salmon Dress Watch

Everything arrived un pristine condition, packaged amazingly.

Quality is great with no complaints.

Watch assembly instructions are vague and require external videos for some extra guidance.

Tools are... not bad. Not the best quality, will get the job done. For this build I got a couple of extra equipments like the hand remover, watch pad and lube for the rubber. For the next build I'll also get the movement holder because I struggled a bit with the stem to get it out without bending the hands.

Overall watch quality is great. Not the best strap, but that is easily changeable.

NOTE: you will most likely need to trim down the stem for the crown to be flush with the case. I had to do it, you most likely will too. Using a cutter worked for me, and I eyeballed it with as much precision as I can. I recommend getting the right tools for it, including a filer.

Very good kit

Fine watch, bad directions

Overall happy with this product, but newcomer beware. The parts feel quality, the yellow dial is awesome! But the directions were very vague - talks about sizing the crown stem, but not how to do that - and the tools in the kit feel cheap and also do not come with any explaination about what to use and when.
