good watch casio only bad thing is that I came with the sound off the alarm clock apparently this buys you will be spending the battery and store the seller placed the new battery but threw the spring that allows the alarm and hour when placed back cover nor was the rubber seal that keeps out water, I myself had to take the clock technical service pay for both $ 50 to be fitted the new spring and rubber seal against water, now if it works as it should be the alarm, other resistant recommend good watch.
