Today I am reviewing the Casio G-Shock GD100-1B watch. I've had this watch now for about eight months or so. I've worn this watch every day and it's one of my favorite watches of all time. This watch is pretty oversized but only weights 72 grams which is why I really like it. I have "clubby wrist" and this watch fits perfect and it's not heavy and discomforting like other watches of its size. It has a slew of built in features which I listed above. The only features I really use often are the alarm clock and the time-zone differentials since I have family over-seas.
