You rarely see a Brumer Bros. watch.
That's because they never made them.
While touted as a rare company, the company happened to be a jeweler in Iowa in the turn-of-the-century era. They bought Swiss movements and went from there.
They never seem to mark the jewels, either. That causes me to assume it's 7 jewels.
Stem wind/set. Has service marks till 1951, so someone took care of it for close to 50 years. Oldest service date in case is 1918 (I think).
