Casio G-Shock Analog-Digital 2100 Series GA-2100CM-5A

The Casio G-Shock GA-2100CM-5A in Black is a general release colorway of the GA-2100 within the G-Shock 2100 Series, featuring the model's octagonal bezel case design that references the classic DW-5600 square case silhouette while applying the GA-2100's sleeker and more fashion-forward proportions, with a combined analog-digital display showing both analog hands for current time and a digital window for additional functions including stopwatch, timer, world time, and five daily alarms. The CM designation in the style code typically indicates a camouflage or military-inspired color treatment, connecting this GA-2100 to the outdoor and tactical aesthetics that G-Shock has consistently deployed across its most popular casual colorway releases in the 2100 series. The GA-2100 platform is built on carbon core guard structure providing shock resistance and achieving a case thickness that is among the slimmest in the G-Shock lineup despite the full analog-digital feature set, making it the most wearable and most lifestyle-accessible of G-Shock's larger case models, with 200-meter water resistance and the full G-Shock shock protection standard across the complete construction. At $120 retail the GA-2100CM-5A is available through Casio authorized dealers and select lifestyle retailers globally.
