Case marked Bulova 14K gold filled New York. I believe this movement to be USA made as the dial and movement do not have "swiss" marked on them.
In reply to William, I finished replacing by MikeSoCal
Our movement database indicates 17AE starting in 1929 w/ no jewel count listed. See http://www.mybulova.com/node/957
We have subject example and one other 17AE in our watch database. Other is here: http://www.mybulova.com/watches/1937-Unknown-166 and listed as 1937 by "arrow" date symbol, but the record is quite incomplete w/ no indication of jewel count.
Ranfft doesn't show a 17AE. He lists a 17AH listed for 1953, but it looks much newer than subject movement, has 17 jewels and BXW on balance cock (Swiss).
Your movement pictures has omega and shield. Did you figure out the other possible date symbol on movement?
This is indeed Swiss, a Venus 133. A very good movt, and seems to be as common as the 17AH. Bulova used the raw ebauches from both, in this case the ETA 953 and the Venus 133, and added their own balance with bridge, and probably designed and manufactured the train bridge layout also, either at the factory in Switzerland, or in the US.
We see the 3 Date symbols on the Movement (Crescent Moon, Shield and Omega) together in 1928, 1929 and 1930, and then again in 1938, 1939 and 1940.

3 Stars.
Will,
The Jewel count for the 'CHESTERFIELD' differs and if one looks closely there are subtle differences in the Dial:
1. The Numeral fonts differ.
2. An inboard circle extending from the Seconds register encompassing the Numerals shows on the 'DOUGLAS'.
Is the subject engraved? Yes, it is.
Engraving can be seen on the outer edge of the Case, matching the ad.
Could the 'CHESTERFIELD' be found with theses traits? I say Yes, the Jewel count being the determining factor.
