its a Casio G-Shock with a Velocity Indicator!! Have no idea what I will ever use it for, but I finally got the long awaited GA-100-1A all stealth black G-Shock! I have to say, I liked the look of it since day one when I first saw it, but after finally getting one on the wrist, I am really stoked about it! I never imagined liking it this much, it just feels and looks super special ops commando on the wrist, in a very awesome way. My personal opinion of this model is 2 thumbs up all the way! As for the backlight, I really like it, illuminates the analog hands perfectly and no problem for me seeing it. I really like how the lcd portions of the dial are reversed all black, for anyone on the fence about this model, I highly recommend it! Nice work casio!
