The Namoki MB78 DIY Kit is a beautiful starting point for the aspiring watch builder. It pays homage to some of the most famous dive-watches of the 1950’s, yet it is an extremely accessible build. The bezel and crystal are pre-installed and the stem is pre-sized to make the build simple and quick. The price of the DIY kit represents amazing value and this will prove to be a fulfilling project for all who take up the challenge.

I have created this series of videos as a step-by-step playlist to help you build your MB78 DIY watch kit OR any simple dive watch kit from Namoki or other suppliers. [This playlist does NOT include information on how to install a chapter ring, how to install a crystal and how to install a bezel and spring].
I will list links below to each of the videos. Click on any of these to go directly to the video that you need to watch.
