Review: Perfect everyday watch if you want something rugged without being an eye sore. - Brilliant everyday watch. I have worn it at close to every day since purchasing. Looks, feels and functions just as good as the day I got it. Its rugged enough to not worry about it while living your life, but looks sharp enough to not look out of place in professional settings.
Review: One of Casio G-Shock's best watches! - Great watch! Very lightweight, good-looking, and the screen is highly readable. The best part is that the watch has Bluetooth time and date synchronization! Pair it with your phone once, and it connects on its own at least once a day to sync the time/date. Brilliant! The watch is a winner! I highly recommend it. Don't buy the models with a negative LCD, as they are unreadable. This one has the positive LCD.
