At first I could not set it.  I would have been better off just trying without reading instructions.  Amazon provided me with a Timex support number and with their explanation I was able to get up and running.  I am happy with the fit and the look.  I have a very small wrist, 5 1/2", and it fits with the furthest spot on the velcro.  Thankful for Amazon support.  And, it is important to note, that I am very clumsy when working with anything that requires understanding directions.  I think I will be happy with the functionality.
