LG GD-910 3G Watch Phone (2009)
At CES 2009, LG Electronics demonstrated the GD-910, the first true 3G phone watch with touchscreen and video calling capabilities, bringing Dick Tracy's 2-way TV phone to reality. It runs on its own proprietary OS.
At almost $1000 and with no data capabilities, the GD-910 is more of a novelty than a practical smart device.
