Review on Garmin Forerunner 25 Replacement Band: Compatible Wristband for GPS Running Watch - Mans Strap (Black) by Scott Goff

This is a universal strap and you need to be careful because there are 2 sizes of watch straps of the predecessor 25: a large loop for men and a small loop for women. There isn't much information on watch band sizes, and it's safe to assume that all Forerunner 25 models share the same band size. However, this is not the case. The one I bought is large so I had to cut off the rubber ends that the mounting screws go in to fit the small one. Cutting the elastic will loosen the attachment loop and after a short time you will have to buy a new one. So do not buy if you do not have sizing information. The soft silicone feels brittle and if you pull the band hard it will break. The photo shows a comparison of small and large sizes, so you need to know your size before buying.
