G-Shock GA-2100 'CasiOak': unisex 49.3 x 44.4 mm metal-bezel octagonal case, dual analogue-digital 3D dial, world time, shock resist, and LED auto-illumination.
The GA-2100 -- nicknamed 'CasiOak' for its octagonal case silhouette -- is one of the most talked-about G-Shock designs in years, and this replica faithfully reproduces its clean, contemporary geometry. The metal-reinforced octagonal case measures 49.3 x 44.4 mm at a slender 11.8 mm thickness, making it genuinely wearable for both men and women. The three-dimensional dial integrates a striking layered design with analogue hands over a digital LCD, giving it a depth and visual interest that flat dials cannot match. All display elements remain crystal clear through the mineral lens. Fully packed with G-Shock utility: shock resistance, LED auto-illumination, world time, full-auto calendar, countdown timer, stopwatch, multi-function alarms, and hourly time signal. Packaged in full retail configuration.
Yes, the slim 11.8mm thickness makes the 45mm-wide case wear much smaller than it sounds. It is popular on both average male and larger female wrists.
The band is carbon-core resin, making it lightweight and durable. It uses a standard 16mm spring-bar system at the lug ends, so aftermarket straps fit easily.
Yes, the EL backlight illuminates both the analogue dial area and the digital segment display simultaneously with a single button press.
