This happened in Germany. From the translated report:

Her watch was equipped with a fall detection system and alerted the emergency services after the fall. A dispatcher in the control center accepted the emergency call. He heard a Watch announcement telling him that a person had fallen heavily. The Watch also transmitted the coordinates of the scene of the accident.

This never stops being cool to me. When I read doom and gloom reports about Apple’s ability to innovate, I see stories like this crop up and think, “Not so fast, curmudgeons!”
