This is a really weird and spectacular little Casio that I have only seen this one example of.
It's metal, and let's you sequence beats. Only two tones, high and low, you,re not making great music on this. But it is just completely unusual.
I just put in a new battery. The watch has surface scratches and wear, but overall is in great shape.
There is one issue with the watch - the light does not work. I was hoping a new battery would fix that, it did not. Still hoping it's a simple fix, but I can't guarantee anything. I'm dropping the price to match.
