In reply to The watch is a Dewey, but… by Alex
I'm wondering if the movement might have been downgraded as an experiment during the early Depression to continue to sell watches, perhaps at a lower unadvertised price.There are currently only 5 watches in the Db counting this one that possess a 7Jewel 10AN. Three of the other 4 are popular pre-Depression models (Envoy, Treasurer, Conqueror and an unknown) , and all 5 are dated 1930 - 1932.
The 3 watches case dated 1930 all have matching 1930 dated movements. The 1931 and 1932 case dates have 1931 dated movements. It seems all of these were advertised with a 15 jewel movement and they all appear to have been 10AN's. In my opinion, this is either an extraordinary coincidence of replaced movements matching case dates, or the 7J movements are original to the watches.
Just thinking out loud.
