Vintage electronic watches on display at Casio founder’s home

June 6, 2015

Apple has apparently overcome reliability problems with some of its Apple Watch components and will begin selling the product in stores this month, according to the Wall Street Journal. If you are more interested in vintage electronic watches, you’ll be able to view some this month, if you can get to Tokyo.

Jun Hongo in the Journal reports that the Toshio Kashio Memorial Foundation will hold an exhibition of Casio watches that were state-of-the-art 40 years ago. They offered a calendar, voice recorder, and pulse-rate detector. The exhibit will take place at the former home of Toshio Kashio, who founded Casio Computer Co. with his three brothers in 1957. The house was turned into a museum—the Toshio Kashio Memorial Museum of Invention—after his death in 2012.

The foundation reports that Kashio was inspired by Thomas Edison and, with his brothers, build the 14-A compact all-electric calculator in 1957. During his life, he earned 313 patents, including joint patents. Watches in the museum’s collection include the Casiotron (1974), which automatically determined the number of days in a month, ans the BM-100WJ, which included microchip pressure sensors to determine altitude and water depth.

Hongo reports that the watch exhibit will open June 10.
