Here's an easy one - 1966 Counselor "A".
Intertwined square and circle case is unmistakable and correct me if I'm wrong, appears to have only been marketed for one year. Replacement band was on watch when I received it, and is as close as I can currently come to the original. A nice crisp example that keeps accurate time.
Reference ad also dated 1966.

Well that is different, very cool! Very 60's with the textured bezel.

Very distinctive. Solves the age old argument of what shape to get, square or round?
Get both.

Sorry Stephen, I'll try harder to find tough ones to ID :0)
Clock is indeed a great find (with a matching store name to an ad)!
