The next Apple Watch will have a camera and more sensors.

Apple's second take on the smartwatch will be unveiled in March, and could ship by April, according to Mark Gurman of 9 to 5Mac. The new version of the watch is expected to feature a built-in video camera, allowing for quick FaceTime (or "wrist time") video calls. There are also rumors that the watch could support special "smart bands" packed with sensors that can do everything from monitoring blood pressure to body temperature.
