Samsung has filed a patent for a Galaxy Watch with a rollable screen.
The watch looks like an average round-faced watch except that it can extend into a pill-shaped oval that's 40 percent larger.
One of the drawings in the patent suggests that the larger screen could be used to watch videos.
There will be a front-facing camera in the middle of the watch.
