      Hi guys. Been a few days since I been on the forum. The wife has been keeping me busy with honey do’s getting things ready for our daughters graduation party. Glad that is over with. I have not started putting the watch back together yet, still waiting for a couple of things in the mail. Question, my watch is an Illinois 15 jewel, 16s, made in 1914. I found a placed to determine the year but can not find where or how to deteremine what model it is. I am waiting for a caliper to measure the mainspring because when I look them up there are several for the 16s. Any helpful tips?

        Hi KyBill,
        There are a couple of good books available to help identify American movements. The one I use most is “The Illustrated Manual of American Watch Movements” by Swigart Co.” I might be able to help identify it for you if you post a pic up here. Also the serial number may help. You put a pic of it in another post but that was the dial side only.
        We may be able to nail down which mainspring you will need.
