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.

Review: Great quality - This is a great everyday sports watch. It feels durable, comfortable to wear, and looks good without being too bulky. It keeps time accurately and handles daily activities really well. I like it a lot and would recommend it.
Review: Nice discrete G-Shock stealth that hides its size, and is care free comfortable. - This thing looks and feels smaller than it is, the angled roundness and blacked out scheme make it discrete on the wrist, hiding its thickness which is nice. It has all the standard features from stop watch to timer, easy to see even though its not one of the new MIP displays. It has acceptable for me viewability in low light, its not going to be perfect but that's the price for discrete inverted display. It helps that the cuff band is nice as it curves around the wrist instead of bending against due to cheaper watches floppy hinges. It makes it more comfortable and sit more appropriately on the wrist. The time is at the bottom and so closer to the front of your wrist, easier to see quickly. Its soft extra wide and more premium feeling than the cheaper watches. The backlight is very bright and clear. The few gripes are this, it doesn't show the clock time in timer mode in the corner like with the squares, it just has animation there instead, and the timer doesn't have an auto loop cycle. I've included a low light picture for reference. Very good day to day watch.
