Hi Krewblink! Welcome to the forum. Yes, LED watches have a good value, especially that nice Compu Chron. Both watches are in very good conditions and it seems that the Hantronix uses also a Hughes Aircraft module, but I'm not sure. (the Compu Chron does though, it uses the same module used also in the Wittnauer Polara series and in many other LED watches)
Their value is around $100/150, but with the original boxes their value can rise. By the way, they're in the wrong category, as they are not LCD watches. They should go in the LED watches category!
But I must congratulate with you, they're in pristine conditions, only the Hantronix seems to have some scratches on the filter, and nothing more.
The other friends of the forum will be able to tell you more info about the Hantronix watch.
