Case SN gives us 1945, but mvmnt. has 49, giving 1949. Original band with "1/20 12K TOP" and "(R)" stamped on the inside. Only one correct hand, the minute hand, zero case wear and very minimal band wear. "SPENCER".http://www.mybulova.com/sites/default/files/vintage_ads/Bulova_AD_1946_4.jpg Light wear to numbers, but dial is good. So, how do you date a watch with a replaced movement?
