The band does NOT fit my UN 353-66 marine chronograph watch. While I knew I'd have to reduce the width of the notched end to fit my watch, it is also too wide across the entire length of the watch, making it difficult to fasten the screws throughout the band. The smaller (less wide or notched) end that attaches to the watch itself, while too wide (again, I knew I'd need to cut this to reduce the width) doesn't have the notch/wide nipple that the standard UN band has, so that it doesn't fit as well as it should even after reducing its width to fit the watch.While the spring tool bar is helpful, you also need a small screwdriver (which I had) that ideally should be included with the band.
