Roger you have a 15 j. watch. An easy way to tell is by the center wheel. If it was jeweled it would be a 17 j. watch. Yours is not jeweled so it is a 15 j. watch.

Thanks Harv,but the center wheel is jeweled. The
picture has a shadow there. Will post a better one.

Roger

Thanks for the better picture Roger. The only way you will know for sure is to pull the dial and count the jewels. I have a 16 j. Columbus. We originally thought it was a 17 j. until I pulled the dial. The center wheel was not jeweled on that side. On these old watches you sometimes have to count the jewels to find what the correct count is. Many are listed as 13-17 and can fall within that count.

Harv, I pulled the dial.

Roger

Roger you have to pull the cannon pinion to see if the center wheel is jeweled.

Looks like it is even marked 17 jewels , looks like a rare , make that MEGA-RARE ULTRA low production prototype illinois

Kevin,it is marked 17 jewels. I doubt it is a rare
prototype. The Illinois records are not 100 % correct. Just confusing at times.

Roger

They where railroad watch inspectors.

Thanks Eugene for that info. I thought that they were but could not find that information.Looking in all the wrong places I suppose.
