The dial is painted, the hands are actually metal frame, and the luminous paint is a wax that is put on the hand kind of like a soap bubble.
The luminous material in the paint is very dead, as the hands and digits no longer glow at all. I guess there is a limit to how long ZnS:Cu can take the exposure and still glow. -Chuck Harris Tom Miller wrote:
