Casio brought an electronics company's imagination to the wrist, moving from calculators to the calendar-equipped Casiotron in 1974. G-Shock toughness, Databank utility, and affordable icons such as the F-91W turned the company into a digital-watch giant whose early modules and resin-cased designs are now a distinct collecting field.
