Years ago a private investigator in a yellow coat and hat named Dick Tracy used a watch to make a phone call, and then everything changed. Of course, Tracy is a fictional character and that smartwatch never actually existed as a product someone could buy (especially not in 1990 when the movie came out). But the dream of achieving that goal, of making a call (or answering one for that matter) on your watch was born. The good news is that we live in a reality where that's an option now.
