Came across this article yesterday while searching for a new rubber strap for my daughter's watch. Found it mildly interesting and don't recall seeing it linked on here:

I'd say I use rubber straps far more than any other type, mostly because it's so practical and also dresses things down a bit. What's your preference - rubber bracelet or leather?
