I'm trying to remember the name of a 70's or 80's TV show where a man used his watch to turn invisible. I think he had been struck by lighting while scuba diving and it made him invisible and some how the watch regulated this ability.

Gemini Man (http://www.imdb.com/title/tt0073994/)

Yet it is Courage" from 1984. I sore it first time in 1998

Gemini man was avalible for $3.95 here in australia about 5 yrs ago but they removed it from shelves as it was selling very well.
