This one looks like it spent most of it's life in the sock drawer. 1924 Pat. dust cover in place and it is currently keeping near perfect time.
White gold plate with engraving on vertical crystal sides and a satin finish on the horizontals. Plain white face with lumed numbers and hands. Curved to fit the wrist case back is single hinged to bezel.
I assume this is a form of the ladies "Sport watch", but am unable to ID it. It appears this is a first for the Db.
Purchased on an obvious late 50's expansion band that I removed - assuming the original was likely leather.

Debutante variant was my first guess. There appears to be multiple examples in the "unknown drawer" with different faces (plain and embossed) and case engraving. Some of those may need to be re-evaluated and possibly be ID'ed as Debutante. I find plain case and engraved on all 4 sides of crystal, but none like this one yet.
Maybe some day an ad will surface.
