The G-SHOCK GA2100 in monochromatic black appeals to those who don’t need a watch that announces its presence but instead need a watch that’s admired when noticed. Built with a Carbon Core Guard structure, the GA2100 offers incredible strength that lives up to the G-SHOCK standard in shock resistance. Its compact form is not only tough, but it also boasts 200m water resistance, world time across 31 cities, Super Illuminator display, countdown timer, stopwatch, and 5 daily alarms.
