Citizen in Japan announced the I VIRT M [JP], a new model in their series of Bluetooth watches that so far are available in Japan only. I am not sure if this is something many people anywhere would want, but the watches make it possible for users to interact with their cell phones.
For example, you can see incoming mails, SMS, news, and other information on the display. The watch can also be used to remotely make pictures with your cell phone, adjust its volume, set it to silent mode or check its battery level. Again, I am not really sure if all of this is necessary.
Unfortunately, the I VIRT M is only compatible to a number of cell phones offered by SoftBank in Japan. It goes on sale July 1 in black or silver with an open price model.
