One man is thanking his Apple Watch for saving his life. James Prudenciano, 28, was hiking along a trail in New Jersey when he slipped over the edge. When he fell, his watch called 911. Rescuers found Prudenciano at the bottom of the cliff with serious injuries. “I'm actually holding on, this watch is right at my face and it said, '911 what's your emergency.' And I’m like, ‘Wow, this is an angel’“. Apple's series four and later watches all have the automatic SOS feature.
