I have been wearing these Casio digital watches for many years. The strap has always been the weak point. A replacement strap costs about as much as a new watch. After many years of use, the small band that holds the end of the strap in place broke on the Casio F105 I had been using. In fairness, it probably broke because I caught it on something. It is not acceptable to have the end of the strap sticking up so a new watch was in order. For what it is worth, the old 105 was made in China and the new is from Thailand. I am unhappy that the blue illumination on the new watch is only about half as bright as the illumination on the old. Why? Is Casio trying to extend the battery life? I prefer the brighter illumination and replacing the watch or battery more often. Actually, I have never had a strap outlast a battery. I buy this model because the blue illumination works. I have found that models with the small LED on the side which emits white illumination are difficult to read in the dark. I liked one of my very early Casio's that also  included a count down timer. Why did Casio get rid of that?
