  • Great watch for the price!
    Verified Purchase

    We like this watch and have had a few in the past, they are good for someone in the construction trade, they hold up well, the only reason we bought a new one is the old watch face was marred from weld sparks.

  • Not broken yet!
    Verified Purchase

    Finally a watch that my husband has not broken right away! He likes the look, and the light is very bright. The band concerned me at first because he usually doesn't like the feel. But, he seems to be fine with it. Hopefully, it lasts longer than a year!

  • Almost a great watch
    Verified Purchase

    While the watch has many functions, some of the most important to me are the various audible features, including multiple alarms, hourly signal, count-down timer, etc. Unfortunately the "audible" electronic beep is a misnomer as it is nearly impossible to hear, rendering these functions useless. Previous Casio watches had audible alarms that were distinct and relatively easy to hear. I returned the watch, but the replacement was no different. Only by placing the watch next to my ear could I detect a very weak beep. In my opinion, the product should to be recalled.
