It's a complete Lone Eagle series III watch (without bezel crossbar chevrons). We have a lack of ads for the early 1930s. In all of the ads for the LE III the vertical engraving is the same. The 1933 ads show a LE III without chevrons (same vertical engraving as your watch). If your watch was 1933 manufactured it would be a Lone Eagle III. I have a 1931 two-tone Lone Eagle III (same vertical engraving pattern as yours). We have a few Lone Eagles stuck in limbo because of no bezel crossbar chevrons. I am not so pragmatic as to say these watches can't be Lone Eagles. Comparing the 1931 Ad & 1933 ads indicate to me that these watches are Lone Eagle varients. None of the period ads show another named watch having the same shape.
Steven, I don't see any 1933 Lone Eagle IIIs with chevrons
resembles the 'GLADIATOR' -
distinct lug difference to the LE III + no horizontal bezel embellishments.
I agree the Case design does look similar the 1933+ Lone Eagle ads, but that would make it a Lone Eagle IV (currently) as this design differs from the 1931 Lone Eagle ads.
