Re: So how did the Astron work?

There were integrated circuits by the mid-1960's, but not really economically practical at the time for commercial products. There is no way a standard DIP logic chip fits into a watch case to make a circuit on a printed circuit board, so some custom silicon would have to be etched to do the project. I would guess there was at least a partial integrated circuit in that chip if this is what was done.
