“Measurement on 15 year old Casio Digital alarm chrono was exactly 18mm. Band feels more flexible, stronger and more comfortable than the original Casio band which cracked badly in two places and eventually broke. Found fitting the 18mm replacement band was easier using a couple of miniature flat blade screwdrivers as the space for the spring bars was fairly tight. Excellent design on the 2 band retainers with slots to hold them in place and a great colour range. Bought a second band for another Casio digital. Also very prompt and efficient delivery.”
