Bulova 1948 Brewster
II have two of these similar watch cases and bezels and three different movements and case backs. The subject watch question is the first photo - a 1948 dated case with a 1947 dated 15J 10BC movement. In the second photo I show both my complete watches (L: 1948 Brewster; R: 1960 Unknown; Middle: 1946 dated 15J 10BC with a case back that starts with a "5" for 1945. The case back fits the Brewster bezel. The third watch on the right is a 1959 (L9) dated case with a 1960 (M0) date 17J 11AF movement. The third photo shows the this subject watch in comparison to the 1960 dated 11AF watch. The bezel is only slightly different in the lugs and in the crown area - otherwise they are exactly the same size and take the same crystal. I could not find any similar bezel and case for 1959-60 so I'll post it as an Unknown...however, I did want to point out the similarities between the two watches.
