Steve MiddlesworthAndrea,
The ones that are marked with "Motor Barrel 60" on the barrel bridge are called the Type I. With that marking and the "60 HOUR" on the train bridge are the Type II. If it is only marked "60 HOUR" on the train bridge it is a type III. This holds true for the 19 jewel and 21 jewel 60 hour watches as well as 23 jewel. Regarding production of the 23 jewel there were 900-1100 of the Type I, 500-600 of the Type II, and about 11,200 of the Type III. Hope this is of help to you.

Steve MiddlesworthAndrea,
Be sure to notice that the Type III shown above is missing the previously used "Co." from the "Illinois Watch" lettering designating this as one that was finished some time after the Hamilton take over. As Lindell pointed out this does not hold true for all of the Type III's but it does for the one shown above, the Type III B variant, which is the less common of the two Type III variants.
In completing this topic, below see movement number 5067943 a
23-Jewel Type III A of which we think 9,000 or so were produced making this one the most common of the 23-Jewel Type I, II, III A and III B variants.

We estimate some 9,000 of the 23-Jewel Type III A were produced...October 25, 2008, 17:19

David AbbeAndrea,As it is clear that you are very interested in Illinois watches. The "Blue Book" is what you need most. My copy of this book is what I have to hunt through to answer my and your Illinois questions.

Andrea SchiaviDavid, thank you for the advise, I find Illinois Watch Co. was such an unbelievable manufacturer of variants and models, but that's where it comes IHC185, to be able to share opinions and all the datas togheter with all its members!

Thanks,
Andrea

Jeff PayneI have a Type III B. Do you all have the serial numbers documented that would tell what serial numbers were used in that watch without the "Co"? And which serial number was the first?
thanks so much,
Just joined!

Wesley SimmonsI currently own the bunn special 23 jewel 60 hour type 1. It works flawlessly and keeps better time than my modern eta 2824. I had it worked on by the good people at the Illinois Watch Company. They have a very nice website and have rather low prices compared to most. I just wanted people to know about them they are a small business in Illinois. I cant say enough good things about them.
