This open-face pocket watch was made by Illinois Watch Company in Springfield. The movement is a grade 69, model 6, size 18, with 17 screw-set jewels. Serial number is 1738812. It has a compensating balance with micrometric regulator. It is a full-plate movement with going barrel. It runs but loses about a minute or two per day depending on position and should be given a standard service before being used as a daily-wear watch. The case does not have a separate back; instead it has an internal ring into which the movement is mounted (commonly called a “swing-out case”). You must remove the bezel, to both set the time with the set lever, and to swing the movement out. However, before swinging out the movement you must also pull the stem out slightly, so that the internal end of the stem will clear the case ring as it swings out. If you do not pull the stem outward first, then swinging the movement out will bend it. As mentioned above, only the little lever located at the #2 marker next to the dial will allow you to set the time; pulling the crown outward only allows clearance for the case ring and does nothing else. Cosmetically, the crystal has been replaced so it is clear as new. The case presents well and has only one small ding on the back. It polishes up nicely and the crown, stem, hinge, and screw-down bezel all function perfectly.
