Here's a few auctions that might give you some ideas. I used to tune into a watch show from time to time, until the independent cable channel was taken over by NBC.
Ocassionally they'd have some vintage railroad watches for sale. A watch couldn't be called a rairoad watch, unless it was accurate enough. So these watches would have high jewel counts.
Illinois, Hamilton are 2 makes that I remember.
