The watch, cosmetically enhanced for the show is a Hong Kong made LCD model sold under a variety of brand names (Nelsonic, Gala, Advance, Quasatron, etc.). But this gadget watch is pretty neat in its own right–it has a built-in AM radio. Plug a set of headphones into the hole on the left and tune the dial…we recall this one being a great diversion in our junior high school Algebra class.
