Casio developed the G-Shock brand of watches in 1983 to realize the new concept of a tough watch that would not break even if dropped. Since that time, the brand has continued to evolve, with advanced functions, construction and design all based on shock resistance. Casio has led the way in introducing electro luminescence (EL) and light emitting diode (LED) technologies for the luminous elements in watches, improving the visibility of the display in dark locations. The new GD-100 lineup uses a high brightness white LED as a backlight for the digital display, a feature which expresses the toughness that G-SHOCK represents, in the form of bright light. In addition to EL lighting elements, LED lighting elements are commonly used as backlights for digital watches, but it has been difficult, on the low power available to a watch, to achieve high brightness with LEDs. They also face limitations when it comes to the color of the luminescence.

The GD-100 lineup boasts a comprehensive range of functions including a world time function showing the time in 48 cities around the world, five alarms, a stopwatch, and a countdown timer. There is also a flash alert function that blinks the backlight with the sound of the alarm or the time-up sound of the timer, and an auto-light function which automatically illuminates the display when the user tilts the watch toward the eyes to check the time.  The body of the watch has a round shape with large, easy-to-use buttons. The face design features five round LCD windows of different sizes all arranged in a row, which give the face a three-dimensional appearance when the high brightness LED lights up. The lineup includes a model with a sharp looking white LCD readout on a dark background, or inverted LCD. This watch has 5 daily alarm which reminds you about recurring events with an acoustic signal at the time you have set. You can also activate hourly time signal that indicates each full hour. This model has 5 independent alarms for flexible reminders of important appointments.
