ANALOG-DIGITAL - GA-2100 SERIES - GA2100-4A

From G-SHOCK, the toughness watches that continue to evolve in search of ultimate strength, this model uses a carbon core guard structure.
The case is made of fine resin containing carbon fiber that, although lightweight, exceeds the rigidity of normal resin. Prevents damage and deformation from impacts to protect the internal module.
Additionally, the two-layer structure of the back cover also guards against impacts to the back of the watch. The shock-proof button structure also allows the exterior to be designed without a button guard.
The design features a three-dimensional dial and a bold arrangement of large front buttons. Finished with a tough design that creates a powerful look.
A model that combines the shock-proof G-SHOCK structure with an urban outdoor style.
