But who would like to order this clock itself, should know that this Casio clock is more suitable for slender wrists, because the clock is quite small itself.
Unfortunately, the front of the clock begins pretty quickly scratch, but this did not bother me at least, and for the price you can not complain really big.
So overall a worthwhile investment if you're looking for a good and practical clock!
