Here is an interesting watch. We have the same watch listed in the unknowns https://mybulova.com/watches/1935-unknown-6131. It has a possible ID as an Everett (or could it be Everest?) from the crystal catalog but no confirmation. The case and case back is 10KT yellow gold filled. Tee dial is white with exploding stick markers except for the 12, 3, 6 and 9 markers. The movement is a 6AF 17J with a triangle date code. I would love to find an ad for this one.
