This watch is a worthless, cheap, flimsy piece of trash.  It quit working within one day of me getting it.  The size is not adjustable so unless you have the wrists of a weightlifter it will be too big.  It displays the time for about one second, so you really don't even have time to read it.  It's not waterproof, so the first time you wash your hands with it on the watch is done for.  Do not buy this POS.
