I couldn't wear this watch strap as only 1 of the 2 parts of the strap could attach to my Garmon Forerunner 645. The rim of the leather protruded too far to insert the spring pin into the watch. The pins also didn't spring back as usual. They had to be pushed in both directions. I sent the group back and now there is a new one. To be honest, I have little hope that it will get better.
