Information about the Gear has been leaking out for weeks in bits and pieces. The Android-powered watch will have an AMOLED display, slightly curved to better fit your wrist. But nobody seems quite sure about the size and shape.

Design patents filed in Korea (originally spotted by the blog SamMobile) show a futuristic look and elongated screen, but they may not reflect the shipping product. Samsung has admitted it has been working on the watch for a long time, so several versions may have been patented, and some may not be quite ready for release; one rumored model with a flexible display, for example, may have to wait until the technology is ready for mass deployment.
As for functionality, the Gear is reportedly not a "watchphone," i.e. a complete smartphone device, SIM card and all, packed into a watch-sized package. Instead, it would be more of a smartphone companion, like the highly hyped (but somewhat limited) Pebble smartwatch, putting notifications, tweets, and texts on your wrist.
