Don’t call it a smart watch. The Casio GB line appeared in 2011 with little fanfare - it was up against devices like the Pebble in the public imagination and so an underpowered smartwatch was of little interest. However, Casio has updated their Bluetooth line with the GB-6900B And GB-X6900B, improved versions of their iconic G-Shock watches that allow you to control your phone from your watch and, more important, control your watch from your phone.
