I picked up quite a tasty 1921 vintage,19-jewel, grade 706, Illinois 16size watch just before Thanksgiving. The case has a nice rosey hue. Haven't given it a test run until today.
Was an Ebay purchase for too cheap.
I find the Illinois "Red Dot" dial to particularly appeal to me. A 21 Jewel Illinois Capitol with with the Red Dot dial was picked up a couple of years ago and introduced me to the style. Apparently the Red Dot dials only were supplied on the mid-grade Illinois watches and shouldn't be found on the railroad grade Illinois watches.
