This one appears to be a first for this variant in the database. Based on the 1973 Line Book BAWD0180 page 14, this appears to be a Clipper BD. The case is yellow gold plate with a stainless case back and a N0 date code, I am not 100% sure this case back belongs with this watch. I am inclined to believe this is a 1972 based on the 11ANAC movement with an N2 date code. As purchased the case back was missing the case screw ring which I am needing to find. This one has a beautiful maroon dial with gold accents around the minute track. It is perfect expect for some dust you can see in the pic.

Just as a point of confirmation, I have this watch and it also has a 1970 case back and a 1972 11ANAC movement.I also saw another for sale with a 1970 back (unknown movement year).
