This instructable is pretty much self explanitory. You can use an ordinary rubber band as a watch strap. Get a rubber band as wide as you can find but not too wide to fit your watch. I got my band from a bunch of broccoli which it was holding together at a supermarket Make sure that the size of the rubberband will hold your watch securely to your wrist but not so tight that it cuts of your circulation. You could, if you so desire, cover the elastic band with a fabric or something similar of your choosing. For now I am going to leave mine as is.
