Here is an interesting one we rarely see. Case is stepped two tone hinged with swiveling lugs. It appears to be on the original band, based on this single example currently in the database, that also pictures another (second page) from the internet. Based on partial remaining band pieces pictured, all 3 appear to have had the same band, which apparently didn't hold up well...
Band on subject watch has been repaired in the past (with non-matching links on underside) and shows wear, but is complete and wrist-worthy. Watch is keeping time.
The only ad I find is from 1931. The ad doesn't list a two-tone option, but we have encountered that before.
1931 Edwin, with "Dress Face" option as previously ID'ed.
