Interesting. Outwardly, looks like a 3310 Classic, but, I don't think this watch has an original Time Computer module; there should be a brown plastic cover over the wire-bonded clock and driver chips, and it should be visible at the bottom of both the battery compartments...not so, here (there are no vias in an original circuit board). I'm guessing this a modern replacement (and, so far, no one has gotten the Auto-Command function to work correctly).

I also found a few differences. But for example first Beta 21 watches were 8192 Hz, but replaceable circuit blocks were 32768 Hz. So different revisions do not look alike. Anyway module seems old and circuit block also seems old (maybe not so old like watch) but still can be the later version of module like in Beta 21. Should I make extra pics of module alone?
