I bought two of these watches - one for myself and the other for my grandson.  So glad I bought one for myself and tried to set the date and time before I sent the other to my grandson for his birthday.  Followed the instructions carefully.  As they were relatively simple, it shouldn't have been a problem - but the numbers wouldn't change just to set the date.  I selected this particular brand because it had the best reviews on Amazon; but it's a dud and I'll send both of them back.  It's a pity too because I really liked the style of this watch.
