My 8 year old daughter asked for this watch for her birthday.  My brother ordered it for her.  For some reason, supposedly it was returned to the sender and our account was credited.  So, we had to re-order the watch.  I am not sure if that was an issue with the shipping service or the seller.  But, once we finally got the watch, it has been easy to use with clear instructions and has been a perfect watch for my daughter.  It has definitely received some splashes of water and we have not observed any issues with it.  It is cute and cheery.  It could also work for grown ups.
