Not bad design for 1973 by Robert Reese from Time Computer ;)

It is a very cool and comprehensive design. Funny how he shoved in TWO "=" signs, just to make a balanced keyboard for the drawing. However, the patent is only on the function not the design; otherwise, the patent would be designated with a D before the number and all the various "means for" claims would not be there. My brother is a patent attorney and I worked in the patent practice for many years...you could even find some drawing I made for odd items like maternity mattresses and games during that time. I'm assuming you colored it since US patents have never been filed or accepted in color - strictly black and white. Back then it had to be on Bristol board in india ink...major pain in the arse. One mistake and start over.

Not watch related, but look at this monstrosity we got a patent on back in the day......too funny. "Vehicle Mounted Air Reversing Unit" . How could we say no, the man always carried a wad of cash - we called him "Guade(Guadalupe) the Wad". http://www.freepatentsonline.com/D307568.pdf

Any idea what purpose this 'air reversing unit' was going to serve?

The object of the "air reverser" was, according to "Guad", that as you drove along the air would curve around and help push your vehicle along. Of course that doesn't work in scientific principle but that is not the standard for obtaining a patent, it merely has to be "new, useful and un-obvious to one skilled in the art". So, we had this guy who drove around our town in a full sized van, with this sheet metal contraption that looked like the plenum of a furnace strapped on top. But you don't say no to a man with a baseball size wad of $100 bills. After he got the patent he paid us to try to sell it to aftermarket companies. Some of the stuff we got patents on were pretty cool like games and tools. Others were creepy like the "little man's Urinal" - looked like a metal shoebox you were suppose to have a toddler boy piss in when there wasn't a lav. nearby.

crazy patents everywhere :) some are really creepy.

I colored the Pulsar Calculator just to show how it might have looked like.
Of course they would not patent the design at that early stage when they hardly new how to produce the final product ;)
The Toshiba and Harris micro-chips on the Calculator had 1975 dates so the process of completing the watch lasted another 2 years.
