Casio

With the launch of its first watch in November 1974, Casio entered the wristwatch market at a time when the watch industry had just discovered digital technology. As a company with cutting-edge electronic technology developed for pocket calculators, Casio entered this field confident that it could develop timepieces that would lead the market.

Today, Casio is focusing its efforts on solar-powered radio-controlled watches: the built-in solar battery eliminates the nuisance of replacing batteries, atomic timekeeping means the users never have to reset the time. Recently, Casio launched a series of Bluetooth watches that sync to the users cell phone to automatically update the time. Casio is always moving time forward.

    I bought this to wear with military uniform thinking it was more tan colored as the picture suggests. Showed up looking like a washed out gray/white. Returned it....

    The watch is awesome. Would've given five stars if it were actually the tan-ish color in the pictures but it's not. It's sort of like a cream-ish light gray.

    I only have one very small complaint. The color of the watch is different then it is in all the pictures I've seen. It's almost a white. Other than that it is a great watch that can take abuse no problem.

    I have had this g shock for about 3 months and I really like it because of the cool color and the analog and digital clock but there are a couple things that I would definitely change. The backlight does not illuminate the numbers up nearly enough. I was running at night and I couldn't see the time. Also, when the minute hand is around 40 it blocks the digital clock which can get annoying. So its a nice looking watch but there is room for improvement.

    Marines, the color of this watch is not the color in the photo (Coyote Tan). This watch comes in a greyish bone color, photo will not work in uniform.

    Nice looking watch. It's a G-Shock what else can you say. Great quality and very good looking watch. It's my second watch. My son borrowed my other G-Shock about a year ago and I realize I'm not getting it back so finally decided to purchase another one. I'm very happy with the look and feel of this watch. Very light weight and a very nice size on my wrist. It has the typical features for a G-Shock that doesn't break the bank and I really only require the basics of this type of watch. I really love the color of it also, others have complained that it's too light and almost white looking, well definitely not white and the color is a light sand color which really looks great in my opinion. I really didn't want a white watch and was pleasantly surprised when I got it and it was a nice light brown/sand color. It has a nice size and looks good on a average size wrist. I'm tall with average size wrists and this doesn't look overly large which is very nice. You really forget it's there because it's so light. One thing that I probably missed or didn't read is that the numbers on the dial glow when in low light/dark rooms. It doesn't last long but was a nice surprise. Also the light is enough to light the hands on the watch but do not light the digital part which in any case would be hard to see without a super bright light built into the watch.
