Hi all, This is an interesting one. I picked it up hoping it is a Bulova case and I think it is but would love your input. The case is marked PAT JUN 10 1924 and 14K. There is no serial number on the case and no signature. It has two diamonds and 4 sapphires. The band is 10K. It was sold as not working but it is ticking away : )
Edited: Added an ad for Duchess. The ad is from the partial ad section dated Dec 13, 1929.
