The G-100BB-1A is a more compact version of the ever popular GA-100-1A1. It is still analogue/digital, and easy to read, but the display has been cleaned of all its clutter, making the time stand out even more.

While it has a 1/100-second stopwatch, it still keeps the previously introduced Magnetic Resistance, and is 200m water resistant, as well as shock resistant. This means wherever you are, you can keep the watch on you without worrying about damaging it.

The shape of the G-100BB is quite unique, and will allow it to withstand impact no matter what direction it comes from.
