I bought this strap to fit a Citizen Eco-Drive Perpetual Calendar watch. It was to replace the flimsy and poor quality rubber clasp strap that broke in less than a year with every other day wear. Though the watch is a 23mm width, this strap fits with a very minimal gap if any, and is well made of heavy and durable nylon.

I have encountered no fraying and or any real break down with one month of very consistent wear. One note of caution; the band was scratchy to some degree for the first week or two and can be irritating to other's skin if they brush against it. The three ring version of strap is much better for my under 7 inch wrist compared to the five ring versions which hurt the bone on the outside of my wrist.
