Really interesting watch style wise. Lots of lines and an interesting combination of shapes with a "pizza" dial and stylized "12". Came to me housed in the original clam shell on an older replacement band that I switched out with a period NOS Baldwin scissor band that, for me puts this one over the top.
As far as unique design elements, I think this seldom seen model is right up there with the intertwined circle/square Counselor "A".
