Another watch I owned. It was an AM radio on a watch, circa 1979.
It didn't sound very good, coming from a two inch speaker. And in order to see the time, you had to press the lower right button, which the red digital LED display instantly caused a loud screeching noise that overrode the radio signal when the radio was on.
Reception was very limited (Seattle's KJR and KING, then Top 40 stations, which put in strong signals on most radios in the Lynnwood, WA area were barely audible on this radio. But the religious station two miles away in the nearby Edmonds area came in loud and clear.)
It was also heavy and uncomfortable after a few minutes of wearing......
