Casio G-Shock GA-400 Watches

GA-400PC-8A — Updated June 2023 color!

About GA-400 in Short. Bright and stylish G-Shock for fans to stand out from the crowd. The variegated colors do not bother the eye at all – the designers have done a good job on the color scheme. For intuitive control of functions, the watch has a crown – to activate the timer mode, to change the world time city and to switch between alarms. The readability of the display is beyond praise – this is where the contrasting dial and large numbers in electronic displays come into play. Stopwatch, timer, alarm and world time are just basic functionality for little money.
