Laser projection wristwatch

An idea whose time has come.
  [vote for,

This wrist-carried timepiece has no dial or other overt display. It does have a touch-sensitive upper surface, and a concealed microphone.

On touching the watch, or on a spoken command, a scanning laser projects the time and date from a tiny window onto any available surface. Since it is a laser, there is no focussing issue.

On the de Luxe version, there is an optional high power fixed beam cut/burn mode for pranksters and secret agents.

       Yes, [xav], seen that - but it only projects a few centimeters.   

       The BorgCo product can project right across a street.

       To avoid tiresome litigation, can I suggest it has a warning sticker (see link) on it?

       [hippo] nice but I hope that sticker isn't on your lab door.

       This, more or less, has been baked as crowdfunding scams: [links]. The scammers were using some kind of magical dark projectors, which this doesn't try to. However, the projection angle problem still applies.
