Clockstoppers (2002)

Until now, Zak Gibbs' greatest challenge has been to find a way to buy a car. But when he discovers an odd wristwatch amidst his father's various inventions and slips it on--something very strange happens. The world around him seems to come to a stop, everything and everybody frozen in time. Zak quickly learns how to manipulate the device and he and his quick-witted and beautiful new friend, Francesca, start to have some real fun. But Zak and Francesca soon find out they are not alone in "Hypertime."
