All black and green 1A3ER

Been looking at GA-2100 for some time. Initially fancy about the green octagon and the orange band but think about how many times I'm going to wear it, changed my mind. Decided with the all black and tiny green option. First look, the green did not appeared as green as we see it in the photo but overall it is still gorgeous. This all black unit can works with suit and tie and match pretty well with t-shirt and jeans too. This is my first step into G-Shock and I'm hooked, my second G-Shock is on the way. Oh what have I done.
