Investigation
Casio was founded in Tokyo in 1946 and launched its first watch, the Casiotron, in 1974. The F-91W, released in 1989, is still in production.
These watches rely on a digital quartz module: accurate, frugal, with a battery that lasts several years.
At this price the case is resin, sometimes chrome-plated to imitate metal. Water resistance is limited to splashes on the vintage models.
