    Black with a red band, this watch was built for the great outdoors. 

    The GA-1000 is a watch Casio created specifically for those who liked the wide open air. Packed with features, it is also very well protected, allowing you to carry it anywhere! 

    When you’re outside, your watch is usually very vulnerable. A normal watch can get scratched up for any number of reasons. Casio used to just go with a mineral glass (which, admittedly, was enough thanks to its scratch resistance. In this case though, they went with a combination mineral/spherical glass. 

    If, while you’re exploring, you feel like taking a dip in the ocean or ravine, you don’t need to take your watch off. It has 200m water resistance, meaning you can swim with it without worrying about the watch being flooded. 

    With a digital compass built into this watch, you can explore to your heart’s content, and not have to worry about getting lost. 

    These are just a few of the features available for the GA1000 series. For a complete list, please scroll down.

    1. Numbers actually light up! review by on

      This watch looks great. It has so many feature and when you click on the light button, ALL the numbers glow. Very easy to read. Usually g-shocks nowadays only light up the bottom so that was a great surprise!
