The dawn of wearable computers

If you deem your new smartwatch the most futuristic piece of technology around, better you have a look at this strange thing dating back to the good old Eighties. It's the UC-2000, a wristwatch wearable computer introduced in 1984 by well-known Japanese tech company and watchmaker Seiko.

I love these things. They're not exactly pretty, but its designers and engineers must've worked within some insane limitations.
