Casio GA100-1A1 Ana-Digi 3-Eye G-Shock Watch

SKU #: Casio-GA100-1A1
Living up to G-Shock’s reputation for big case designs, comes a revolution in case size with the introduction of the X-Large G. This Ana-Digi, “three-eyed” monster measure in at a whopping 55 x 51.2 x 16.9mm size, with an attention to detail, that is second to none. Large anti-skid buttons provide easy operation, embossed indexes gives a 3-D look and a rivet bezel design adds strength to its overall appearance.

    I would recommend this item to a friend.

    If only the digital display were a little brighter

    Everything about this watch is great except that in low light conditions it is difficult to read the digital display even with the backlight on. The picture shown is true in lighted conditions but not so in low light which is difficult when working mostly at night. Other than that it is a great watch.
    Great design and look Lots of features Strong build
    Hard to see digital display in low light conditions even with backlight

    This watch is great! I've had it for almost 3 years now. Same battery. It has survived a beating that's for sure! Worth the $100.00!

    More bang for your bucks than the Luminox Watches. Great features for AnaDigi GShock Watch. Easy read time with the white needles on all black face in low light. Needs longer wrist bands for adults fitting and better seals for waterproof. Mine hand to be repaired under warranty after 8 months of under moister trap inside the screen.

    Super good looks (almost completely blacked out). Great big face (easy to see). Only problem is led backlight (could have used Casio's Illuminator tech more, but not a dealbreaker)
