I looked for 30 years for this Casio with a count down timer from the movie "Blue Thunder".
About 10 years ago, I was going to watch my neighbor's house while they were away and feed their dogs.
When he gave me the key, the key fob was "the watch".
I yelled "holy schitt, that's the Blue Thunder watch!!"
He didn't even know or care, but he gave it to me.
I had a Casio watch I bought mid 1980s. It had daily alarm that I used to wake me up every morning, stopwatch, countdown timer. It said the battery would last 5 years from time of factory install. The battery last about 7 1/2 years. I had the battery replaced and then I lost the watch. Bummer.
