NOTES:  This model has the rarely seen 21 jewel 10AN movement.  Like the others I've seen with this movement, it has no movement date code or serial number.  Other examples of this movement in my collection can be viewed here:  1931 Unknown1931 Unknown, and 1932 President


The ad below is the first we've seen of the Edwin.  It varies from my example in that mine has a two-toned, engraved case and the dressier dial and hand combination seen in many late 1920s and early 1930s watches.   I am aware of another example of this case, which has a two-tone, unengraved case and a dial with raised guilt numbers and hands.  These examples may be variations on the Edwin, or they may turn out to be different models altogether.  During the 1930s, Bulova made quite a few models with engraved and unengraved cases, different metal colors, and varying dials, and used the same model name for all such style variations.  Well known examples of this phenomenon include the American Clipper, Minute Man, Phantom, and President, among others.  The Edwin may be another example of that phenomenon.  So, for now, I am tentatively identifying this watch as an Edwin.
