Check this cool watch I saw in a Facebook Group post today. It’s a watch but it’s also a TV! This was back in the days of the Sony Watchman.
Unfortunately to get the TV component to work you needed to hook up this walkman size contraption that contained the tuner. But the watch itself was running with a liquid crystal display.
There was even this Casio watch that in the 1980s which not only had a touch screen but could recognize numbers drawn on its face for the calculator function.
This kind of tech was so magical to me as a kid and there never seemed to be an end to all of the cool new innovations coming out of Japan. My Dad traveled to Asia frequently and would always come back with stories of all of the cool tech he saw in the shops.
