Bright finish case measures 29.5mm lug to lug x 15mm non-inclusive of the Crown using calipers.
Ribbed dial shows raised gilt numerals, hour and minute hands are black modern.
Caseback is stamped 'Bulova Quality' AAA with a patent date of June 10 1924.
It doesn’t happen very often that I am confronted with a model I have never seen before but this is one of them. It seems a simplified version of the “Lady Bourbon” without the wings (sorry, somehow I can’t copy paste a link here using my mobile phone, will try later from a desk top). Hence, unknown!

Is it for sale by any chance?
Never seen anything like it. Unknown for me.
Me either.
Searched the ads for a match until My eyeballs bled, twice. Nothing, nothing even close.
My intentions upon return here were to take inventory of My collection and sell them off. I've sold 2 (models I had more than one example of) and bought 6. ha!
I do enjoy the gilt numeral / black hands (dress) combinations of these late 1920's early '30s watches.
back down the rabbit hole...
I wonder if the 2nd and 3rd steps shown on the 'Lady Bourbon', are infact 'attached' to the watch via the bracelet?
Are the 2nd and 3rd steps sitting atop the lugs rather than apart of the actually case?
Here is a photo of the other unknown with the 2nd and 3rd steps. Look at the rear view showing the lugs similar to the subject watch.

i saw the 2 more step are from the bracelet too. when we see how much near the case are the springbar it does not lie!
the lug placement differs.
I think the steps are part of the case.
