Another one of my "what the heck is that?" purchases. Dial is matte gray around the outside with a polished gray textured center. Indices are yellow with a dot of lume. Band appears it could be original and watch is overall a 9 out of 10 and keeping time. M0 dated movement is like a mirror.
Watch appears in the 1961 linebook, but not in 1960. In 1962 it appears to have experienced a dial change to become a member of the Jet Clipper line. There were 4 versions of this watch in 1961, this appears to be the Calendial "BW". This one is a first for me (and the database), and when compared to the single example of the "AW" in the database, it's obvious this is the gray dial "BW" version.
Ad shows a magnifier crystal, subject watch sports a regular replacement. Based on research, I have to believe this is a one, maybe 2 year production "hen's teeth" watch.
