Casio G100-1B G-SHOCK ANA-DIGI Watch

SKU #: Casio-G100-1B
MSRP: $100.00
Based on the successful analog/digital GA100 X-Large G Series, G-Shock an all digital version large size and wide face not only give a look of power and strength, but make it extremely easy-to-read and use with its oversized buttons. For added visibilty in dark conditions, a newly designed high-density LED light has been employed to light up the dial face from behind. The result is a super luminous display that's a true reflection of G-Shock's desire to keep improving timekeeping.

Exposure to stong magnetism can cause timekeeping to slow, affecting timekeeping accuracy.

    Could not read digital part of watch
    Digital part of watch was not easily viewed. You have to hit the button for backlighting to read the digits. Would like this part of watch to be viewed without needing backlighting.

    I love the matte black finish. Its easy to set the digital and analog time. My co-workers have commented how much they like the way it looks and that it is a normal size, unlike other g shock watches.

    This watch only has an hour hand (white hand) and a minute hand (red hand).It does not have a hand counting seconds. Only the digital screen counts the seconds.
