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. |

[8th of 7] By Douglas Adam's standards, are you sure you are not human? |

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. |
