Here's another late 1920s gem! I believe the case back stamp and number: 8558259 indicate 1928. The movement is stamped 1926 "triangle" with the serial number is hard to see, although I believe it's 89766.
The dial on this one looks a lot like the Clare I submitted earlier, although it is significantly longer at 32.9mm (including lugs) and 17.2mm in width.
I came up empty, finding a reference to this type of case. However, the engraving is only on the sides. Your help identifying this watch is appreciated!
Dear slsummers, a very nice watch you posted. It is part of what I call the Debutante family that had in total 5 engraving styles, this unengraved version being one of them. Several of these model with an 8558 case serial number have been found so far. It is from 1927, recognized by the case signature and normally has a 6AF movement stamped with a triangle and an arrow. Can you have a double check if you find the arrow? I suspect it to be above the second screw right of the triangle stamp. Let us know!
Given Alex's earlier comments, I'm a bit confused about the "unknown" designation.
Are you saying it's not a match/characteristic of the Debutante family, OR are there no ads to verify which one out of the five engraving styles?
It looks almost identical to this one except for the triangle stamp on movement and case engraving pattern: https://www.mybulova.com/watches/1929-debutante-10629
