This is a  very rare c.1930 Elgin Avigo Gents Watch, these were produced from the late 1920's till the early 30's, and are now much sought after. 
 
Some have described this as a Military or Pilots Watch, well it's Aviation linked but not in the sense that this watch was used by the Military, the truth is simpler,  Avigo was a division with the Elgin Watch Co that made Aviation timing instruments and Elgin thought it might be a jolly good wheeze to get some publicity for this division by adding the logo to their own watches. Simple really. 
 
This watch is for its age simply gorgeous it's Chrome Plated case is in very good condition for its age, the dial is pretty much immaculate. 
 
Inside the case is an Elgin USA 485 Caliber 7 Jewel Movement 
 
Overall cosmetically this is in excellent condition for its age and is running very well.
