The Engineer III Marvelight from Ball is based on a theme aimed primarily at pilots and aviation enthusiasts, but is also designed for those who simply want to have a highly functional and beautiful luxury watch. As far as ruggedness is concerned, they are created to have higher resistance than the average luxury watch, especially higher water resistance and impact resistance, thanks to the mu-metal coating.
This Engineer III Marvelight Rainbow Caring has 6 different colors of gas tubes that mimic the rainbow, a symbol of hope and the natural wonder of light. The tritium tubes require no charging and last for a long period of time.
