The Illinois Watch Co. Was bought out by Hamilton, circa 1928-29. The first Illinois watch to be finished by Hamilton was the grade 161. This was basically a Bunn Special 60-hour with a model number given to it by Hamilton. The watch was still marked as an Illinois, but the movement was marked Illinois Watch, Springfield. The abbreviation CO was omitted on Hamilton-made Illinois watches. The grade 161 had 21-jewels. There were 8 versions of the Illinois Bunn Special 60-hour grade 161 produced by Hamilton, including an Elinvar model. Hamilton also produced basically the same movement with 23-jewels. It was the grade 163, and was made in 4 models. One model was not equipped with Elinvar, while the other 3 were equipped with Elinvar. Hamilton had experimented with a 60-hour movement, but I gather it never got past the prototype stage.
This all leads to a question for @Fritz . What is the serial number and jewel count on your Illinois Bunn Special 60-hour, and how is the movement marked? With the CO. , or without the CO. ? Is it a grade 161 or 163. That was how Hamilton marked these models.

serial 5110950.
I checked the numbers and labelling when I first purchased this little jewel, at your suggestion if I remember correctly, and it is a pre-Hamilton watch. Just a plain old type III, 21 jewel, 60 hour, motor barrel, adjusted to 6 positions lump under he hood...
so sad... *sigh*
I was happy as hell to find it as this stuff is pretty thin on the ground in Canada these days.
I figured it out this morning when I wound up my ‘28 Bunn Special.
And so, I present..
The Illinois wind indicator defined: close your eyes and pick a watch from your collection and wind it up.
if you get a cramp before you are done winding its an indicator of an Illinois 60 hour spring.
easy...
Several months ago, a chap from out of town brought me two watches for estimates. One is the subject Waltham pocket watch, and the other was a ‘60s vintage Tudor gent’s manual winder. I prepared the quotes and phoned him. He told me to go ahead with the Tudor, but the Waltham meant nothing to him, he didn’t want to spend money on it, and that I could keep it for parts. Here is the pocketwatchdatabase.com info on it.

I probably have everything on hand that I think I need to return it to health, but I’ll postulate on it for a while before I decide. I might be able to use the case on a Hamilton that needs a case. But this one is an 1877 Waltham, and the pendant on these is different to later pocket watches, and until I check, I won’t know if the swap will work. It is also only a 13-jewel model. Very ordinary R E Robbins grade. Royal Robbins bailed out the nearly defunct forerunner of Waltham, the Boston Watch Co. in the early years. Robbins was a visionary, and he had a great influence over the firm as it transitioned into the firm it became in later years.
The gold filled hunter case is by Dueber, and it is in excellent condition for a 140 year old watch!
Today, he picked up the Tudor and paid me for it. I made him an offer on the Waltham, and he accepted my offer. So it is now mine! (I mighta coulda had it for free, but I’m too honest!)
Nice case, handset and movement.
I don't understand people's motivation when faced with a nice PW.
