    I have a few GA-2100's but had yet to snag this for myself. The bluetooth feature, combined with the solar power make this the best way to experience this model(in my humble opinion of course). If you like this series of g shock, definitely give this a look.

    Very nice watch

    I purchased this watch for my boyfriend. He loves the watch and all of the features. This watch is very stylish too if they don’t like bulky metal watches.
