This band is so awesome! Works perfectly on my Casio AMW-320C. I've had this watch since the early 90's and didn't wear it because the band broke and the battery died. I recently revived it with a new battery and this awesome band and I love it! It's so stylish and classy. My exact same watch is currently for sale at Walmart and various other places. I highly recommend this band if you want your watch to be classy and stylish. The black one is sporty, but not dressy at all. Now I wear my awesome watch all the time.
