A new GG-B100 shock-resistant carbon core guard structure integrates the case. An external structure capitalises on its toughness and lightness. The new carbon case helps to develop a new structure of button. This also enables removing the button guards from the exterior. GG-B100 features a stainless-steel panel back that keeps the watch airtight, as well as a fine resin glass fibre case back that makes it tough against shocks. This design is inspired from the petrol tanks carried on offroad vehicles often used on rough roads.
In addition to miniature sensors that are capable of measuring heading, altitude, atmospheric pressure, and temperature, the watch adds its quad sensor functionality with an accelerometer that can be used to count steps. This supports professional rangers in understanding changes in the natural environment and recording a history of their activities.
