So...there is a story behind this. I've had these pictures for a little while. About 2 years ago I saw this watch go bye and I liked it, but felt he had it as too expensive. Waiting for the auction to end... I missed it by a couple days. I reached out to give him an offer... but he had already sold it for scrap 😞. With his permission I saved the pics and am posting it here.
Earliest case I've seen for a men's Bulova.
Pretty cool... unknown for me. I couldn't read the date code right off the bat.
Guessing... help out guys and gals.
Interesting watch! Too bad it got scrapped. It is a Swiss hallmarked watch. I found those Swiss watches with movement date codes between 1923 and 1925. The 10AA movement I found around 30 so far and all were stamped with the 1924 date code except for one that has a 1925 date code. They were all 16 jewel movements, but the one on this watch is a 17 jewel movement. A first! The date code as visible on the watch is hard to recognize but I would go with the flow of the other 30 10AA movements and say it must be an asterisk. That makes this watch the 3176 as advertised in 1924. This model would become the Banker when Bulova started to give names.
At least we can save the history of this watch.
It is indeed a Bulova 3176 shown here in the May 17 1924 Saturday Evening Post
Also agree with Alex that the date code is likely an asterisk I have a 10AA in my hand as I type. Serial number 124019 and sporting 17 jewels.
