Explore Casio

Casio brought the calculator maker’s sensibility to the wrist: put useful information where you can read it, and make the controls work without ceremony. Its Casiotron, introduced in 1974, combined a digital display with an automatic calendar. That practical streak still runs through the range, from slim resin digitals to watches equipped for navigation, weather tracking, and radio-controlled timekeeping.

The big turning point was G-Shock in 1983. The original DW-5000C established the square silhouette and shock-resistant construction that remain central to the collection. Today, the familiar square shares space with the octagonal GA-2100 family, metal-cased variants, and deliberately oversized tool watches. Beneath those different shapes is the same concern: protecting the module from the knocks of everyday use.

Elsewhere, the F-91W distills Casio into three buttons, an alarm, and a stopwatch. Pro Trek takes a more outdoors-focused approach, with compass, barometer, and altimeter functions on many models; Edifice favors analog displays and chronographs. The contrasts are part of the pleasure: one maker, several very different wrist habits.
