About G-100 in Short. The owner of one of the smallest cases among all G-Shocks. Despite its modest dimensions [49.6 × 47.8 × 15.7 mm], the model is not inferior to colleagues in the shop in terms of impact resistance and security. The dial, although ana-DJ [and hands and electronic display], is not overloaded with information and looks minimalistic. Due to its “secretive” design and brutal shooters, the G-100 is in demand among the military and other security forces. The clock module is protected against magnetic fields. For those who travel frequently, there is quick access to the time in the second time zone. Stopwatch, world time, timer, alarm and calendar – all you get for a low price.

Official Casio Description. From G-SHOCK, the watch that sets the standard for timekeeping toughness, comes the latest models to feature basic G-SHOCK black that captures the essence of one-tone resin. This model is based on the G-100, which is designed to withstand impact from any direction. A simple matte black finish allows the form of the watch itself to come out, while the buckle and buttons have a black ion plate finish. Everything about this new basic black model captures the very essence of the rough, tough basic G-SHOCK image.
