The GA-2100 is Casio's slim octagonal G-Shock, often called the CasiOak for its resemblance to a luxury steel sports watch. Its carbon-reinforced resin case measures 11.8mm thick and weighs about 51 grams, so it wears far lighter than the chunky 6900-style G-Shocks. It pairs analog hands with a small digital window and packs 200m water resistance, world time, five alarms, a 1/100-second stopwatch and a double LED light. Reviewers like the look and the toughness; the common complaints are the dim analog hands at night and the small digital display.
