I second guessed myself a half a dozen times before concluding this is a 1947 Director ("C"?). This was a pretty confusing one, as 3 different watches used the same case with a 21J 7AK within a 3 year period. White gold plate with a slate dial with even numbers and squares for the odd. Lugs are polished and sides are a buff finish.
Statesman in 1946/47 was the same case with a full numbered dial and same movement. It changed to the His Excellency in 1947/48, also w/full numbered dial. Director was in this case in I believe 1945 to 1947 configured as seen in subject watch. Available in yellow, rose or white. In 1949 (by documented watches), the Director went to the small case w/ribs between the lugs and was also available in 3 colors. We have determined yellow was "A" and white was "C" in that style. If Bulova maintained consistency, logic would say that subject watch is a Director "C" in white.
Ad is dated 1946 and shows Director with this face as well as Statesman w/same case and different face. Note ad calls out 3 colors of gold at bottom.
