The all-black model of the GA-2100, commonly known as the Casioak, a popular G-SHOCK model. Brand new, unused. Comes with the case and foreign language instruction manual. It is currently running, but please be aware that it may stop due to battery depletion at the time of purchase. From G-SHOCK, the toughness watch that continues to evolve in pursuit of ultimate strength, comes a digital-analog combination model that inherits the concept of the first model "DW-5000C" and achieves further thinness. It inherits the "octagonal form" also used in the first model "DW-5000C". We have developed a combination model with a simple design that eliminates waste while maintaining the tough structure. Furthermore, the case material uses fine resin containing carbon fiber, which exhibits high rigidity, achieving a thickness of 11.8mm. The color adopts a G-SHOCK-like blackout.
