The Casio G-Shock GA100C-8A is a large ana-digi resin watch built for rough use. A 51mm case, 17mm thickness and 200m water resistance put it in the same class as other full-size G-Shock models, and the shock and magnetic resistance back up the claim. The feature set is broad for the class: world time across 48 cities, four daily alarms plus snooze, a 1/1000-second stopwatch with speed and distance input, a 24-hour countdown timer and an auto LED light with afterglow. It suits people who want one tough everyday watch with analog hands and a digital display, and it is heavier and bulkier than slimmer G-Shock lines.

The Casio G-Shock GA100C-8A is a men's ana-digi dive watch with a dark grey dial and hour index markers. It has a 51 mm case with a fixed grey bezel and textured function pushers. The grey resin strap closes with a buckle clasp. A mineral crystal protects the dial, and the caseback is secured with four screws.
The watch is shock resistant and magnetic resistant, and it is water resistant to 200 meters. An auto LED light has afterglow. It shows the day, date, month and year, and has a full auto-calendar pre-programmed until the year 2099.
World time covers 29 time zones (48 cities plus UTC), with daylight saving on/off and home city/world time swapping. Other functions include 4 daily alarms, a snooze alarm, an hourly time signal, a 1/1000 second stopwatch and a countdown timer. A quartz movement powers it.
