Casio G-Shock GA-100-1A1ER

Casio G-Shock GA-100-1A1ER



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” phenomenon measures 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 it's overall appearance. There are two versions; the GA-100-1A1ER is all black whilst the GA-100-1A4ER has red highlights.

    1. Favourite GReview by
      Have the black version and love it. It has a large face with understated and stylish features - which has attracted a number of compliments. Ths was my first G-Shock (my tastes prior to this have been more 'traditional') but I have since bought more - love the reverse display look on this digital model. Sturdy, comfortable and reliable. The illumination at night is fantastic too - no issues reading the time so far. (Posted on )
    2. Great WatchReview by
      Great Watch love the all black "look" however having read the other review it is clear that both watches have the same difficulty in reading the digital display when dark. The Afterglow feature appears to just be the orange LED light it doesn't actually "glow" and neither do the dials or hands. (Posted on )
    3. mrReview by
      having purchased the black and red watch i found there are certain subtle differences in the models. BE AWARE. One, the black and red model has standard led displays the black one has reverse displays. The black model has an afterglow feature, were as the black and red model has a single led point of light at the six o'clock position.

      The black and red model, for some uknown reason has luminous hour indicators instead of the black models afterglow feature, but even worse the hands are not illuminated - WHAT !! i hear you say, yes, hour hands illuminated, but not the hands.

      To finally finish in low light or darkness even with the single point illumination on the black and red model you will be hard pressed to find the hour hand. Oh yes and no use using the led display, instead for the time as it is not back lit, so all led display functions are unavailable in the dark. That is unless you strap a torch to your watch. Other than the above a nice time piece. Heinnie Haynes it might be worth while detailing the differcences between these 2 models..
