The Casio G-Shock GA-2100-1A4ER stands out in the acclaimed “CasiOak” lineup with its ultra-modern octagonal design, matte black case and strap, and signature bright orange accents for a bold pop of colour. Slim and comfortable on the wrist, the 45.4mm case is constructed from carbon-reinforced resin using Casio’s innovative Carbon Core Guard structure—making it exceptionally lightweight, durable, and resistant to impact. Engineered for all-day versatility, it features G-Shock’s legendary 200m water resistance, shock resistance, and a scratch-resistant mineral glass crystal, making it ideal for swimming, sports, and everyday wear. The analogue-digital display delivers practical functions: double LED illumination for the hands and digital LCD, world time (31 zones), 1/100s stopwatch, 24-hour countdown timer, five daily alarms, a full auto-calendar to 2099, and both 12/24-hour time formats. Powered by a precise quartz movement, the GA-2100-1A4ER weighs just 51g and is finished with a comfortable, secure resin strap (fitting wrists 150–215mm) with a classic buckle. Perfect for those who seek a standout fusion of tough utility and modern style, this model represents Casio’s drive to innovate with form and function—backed by a two-year warranty for confidence on your wrist
