Bulova 1946 Aviator
I'm not quite sure what this is. Possibly a Stamford? I saw an ad for 17 jewels but not 15. Rose gold plate bezel and what I THINK might or could be the original band in rose gold fill. Possible a JB on the trademark? The 10AK 15 jewel movement date is double stamped with a triangle and square. The crown is not signed. The original glass crystal was broken. The hour hand appears to have been replaced at some point as it is bright blue and the minute and second are plum.
I found the double date stamp interesting although I have no clue how often that happened. It could be 1935/36 or 1945/46. I don't believe it is from the 20's because the style doen't look right. I did see a 1936 ad for a craftsman that seemed close.
