This is my second replacement strap for an Observer. The first replacement was a standard strap, a bit more expensive; it failed when the buckle hardware popped out and was lost in the undergrowth, the same failure I had with the original strap. This one was a bit cheaper. Installation took 10 minutes with the help of a teeny screwdriver. Unfortunately, just a few days after installation, the sliding loop that holds the end of the strap ripped, it is very soft and even the edge of the strap was enough to rip it. I think I'll have to get another original strap, even though they aren't that great either. I love this watch, but I wish that Suunto devoted more attention to strap durability.
