    Band Color: black
    Pros: This watch is quite accurate. I've never had to make any adjustments to it and have been wearing it for nearly two years. Still on the first battery. This watch is also incredibly rugged. I am an active, active outdoor adventurer and have ABUSED this watch. It's never once asked me to ease up on it; it just keeps telling me the time. This includes a couple SCUBA dives.

    Cons: The light only lights the small digital display at the bottom of the watch. If, like me, you keep the digital display on the date mode, the night light won't help you much. I don't believe this watch has ever leaked, but if the temperature is cool, this watch fogs up. And finally, if the time is between 25 past the hour and 35 past the hour, don't even think about being able to read the digital display at the bottom; the minute hand WILL obscure your view.

    Overall this is a great, rugged watch for the price.

    This is an excellent watch, and I could not be happier with it. The G-shock series is used extensively by the military, special forces and police, and it's easy to see why. This watch is extremely well built and durable, and it uses only high quality materials (that goes for the band as well.) It's also very light and comfortable.

    The styling of the watch is not for everyone, however. This watch has a very tough, prepared-for-anything kind of look that I love, without being over the top. It is slightly thicker than other digital watches, owing to its armor-like exterior, but this is very subtle. Also, this watch does not have an overly large dial, as has become popular in watch styling lately. But I take issue with the many reviews that have described this watch as "small." These are clearly customers who were looking for the aforementioned large dial styling. I am 6'3'' with large wrists and hands, and I don't think the watch is undersized for me at all (nor does anyone else). At the end of the day, it's a very standard watch size.

    I have noticed that many reviewers are unhappy with the way in which you adjust the analog hands, which surprises me given how little time it takes. I had to adjust mine 11 hours right out of the box, and it took about a minute. I suppose if devoting a minute to setting your watch time is a major issue for you then you should look elsewhere, but if you're like me you won't even think twice about it.

    Finally, some reviewers have complained that the watch is useless at night unless you set the digital screen to report the time rather than the date. But this ignores the fact that there is a button on the side that cycles through the watch's various modes. One can easily use the digital screen to report the date and, when it grows dark, simply press this button. Then just hit the light button and you're in business. Easy as that.

    if you break this watch there is a good chance your wrist is in pain. i own lots of watches and i have many stainless dive watches that look tough and fancy. none can hold a candle to a g-shock. ever. that said, a huge production environment is bound to put out a couple mistakes. it happens. exchange it for a new one if possible.
    i own one of these watches. its not small but it doesnt look too bad on my little wrist. the light doesnt light up the dial-only the digital read out.that doesnt matter too much to me because the lume on the hands stays lit pretty well. the buttons are hard to push for a very good reason-you dont want them to get pushed unless you mean it. in an active environment , this is the way to be (for me at least). the hands stay where they are supposed to...there are some sport watches out there that are cheaply built and the hands will "slip" if the watch is knocked around (im looking at you pulsar)
    let me explain the title of this review here. some people my think that because this watch is made out of plastic that it is low quality. not true in this case. this is a tank of a watch. you could probably run it over with a bread truck and it would be ok (dont try that).
    i am a pipefitter and have had one of these for 2 years and it looks brand new and has never failed me. great price too! casio did not fool around when they built this. we asked for it-they built it.
    if you want a watch that will impress your friends at dinner this might not be it. if you want a well engineered,simple watch that will impress you....this is it. fresh battery every few years or so and youll be pleased as me.
    edit: i now have 2 of these. one is all black and factory and one is navy blue with a black bezel. i bought the blue one on x-bay and tore it down and refurbished it inside and out. i put a horrible picture of it here. its the one in the bush.

    I used to have a great watch collection that started when I was 12 years old. It began with a Casio G-Shock watch that my uncle bought for me as a present when I visited Thailand. He took me shopping in the market and we stopped in front of a watch store. I remember the hot, sticky musk of summer Bangkok weather, ushering us inside the store with its cool air conditioning and ethereal lighting. My uncle looked at me and said that I could pick any watch that I wanted and that he would pay for it as a present to remember my family in Thailand. My eyes wandered and became fixated on a very large, and bulky plastic watch. It looked like something very technical and indestructible, like I had never seen before. I hadn't ever seen anything like it back in America. It had fancy dials, a stop-watch, and a number of cool features and gadgets. It was a Casio G-Shock.

    Over the course of 14 years I had collected many other watches, which I had kept in a watch box. As I grew older and began to work, these watches became much more expensive and fancier. I had watches for specific purposes; ones that I used for working in clinic, watches I wore to social gatherings, during sports, during running -- and a watch that my friend Chris had bought me the day I was a best man at his wedding. I even splurged the day I got into medical school by buying myself a Citizen Eco-Drive watch, solar powered with an alligator skin strap, which soon became my most favorite and coveted timepiece.

    I kept all of these timepieces neatly stored away in my room, until they disappeared this past Tuesday. A indecent excuse for a human being broke into my apartment and stole a large number of things that I own, but most upsetting to me, he took my entire watch collection.
