1970 Chrono w/ very nice complications...Cal 11????
Well just because I haven't seen it doesn't mean it isn't out there. This one is just too cool. It's stated as a stainless steel case, sporting an 11 movement. It was called "bull head automatic", and the first thing I thought was bull#*%!, but after looking a little closer, I can see how someone would describe it as a 1970 Bulova Bulls Head Chrono. Case diameter listed as 42mm w/o crowns.
