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.-- 8th of 7, Aug 10 2017 ASU CastOne http://www.a-su.com.cn/Home/En/os [xaviergisz, Aug 10 2017] Warning sticker http://ledmuseum.ca...er.us/sixth/bsl.gif [hippo, Aug 10 2017] Ritot https://www.eevblog...watch-on-indiegogo/Mentioned in my anno [notexactly, Sep 08 2017] Blamix https://www.eevblog...ed-projects/t39829/Mentioned in my anno.

The BorgCo product can project right across a street.-- 8th of 7, Aug 10 2017 To avoid tiresome litigation, can I suggest it has a warning sticker (see link) on it?-- hippo, Aug 10 2017 [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?-- wjt, Aug 11 2017 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.-- notexactly, Sep 08 2017 random, halfbakery
