I have a Casio MW-600 with a 10 year old battery that refuses to die after 12 years. Like many Casio watches, it used a polymer strap that didn't last long. So far I've gone through two of them. I have a 15mm NATO strap and it works great. If you love your little Casio and don't want to spend money on another polymer strap, I recommend this 15mm NATO strap.
