I searched for over a week looking for the right watch and I have it in the GD100-1B. It looks amazing! I have small wrists and I was very concerned about the size of the watch face looking "chunky" and just out right ridiculous on my arm. Needless to say it fits perfect! I loved the look when I saw it online and once I was able to try it on in person, I knew it was a perfect find. Will review again in a few months and share updates!

I never knew much about g-shocks until I started looking into a durable watch for work. I work at a Florida prison and wanted something tough and functional, this is it. I prefer the negative display (black on black) from a stylish perspective and from a professional perspective for work. I dont really need the multiple time zones but its completely functional. The backlight display is effective and provides the right amount of light.

The watch is comfortable and doesn't look...Read more

I've to mention that this watch is very comfortable and lite for its size. The only minus sign is that the graphics are pretty dim without the backlight which does not concern me much, probably not a good option for people with vision problems. Nevertheless, using the back light will give you a nice an clear view for the graphics. Finally, the watch looks tought and durable and as I've mentioned before is very comfortable for its size.
