Cellwatch Wrist Watch Mobile PhoneSMS Technology of Australia claim they have the world's smallest wrist watch mobile phone in the form of the Cellwatch M500. Not only is it small but also light at 60g and provides a host of features that even many standard phones don't provide. In addition to the 1.5" touch screen, there's a 300 number storage capability, SMS and MMS messaging, Tri-band, support for MP3 audio and MP4 video playback and USB connectivity.
Battery life in standby is an impressive 80 hours with 200 minutes talk-time (using the wired headset). No doubt this reduces when using the Bluetooth 2.0 connectivity.
Supported languages are: Arabic, English, German, Russian and Turkish.
It's claimed the watch will be available from March 2008.
