Rare 1911 Illinois Sangamo, 16s, 21j, Grade Sangamo, Model 5 Railroad Grade Pocket Watch Serial No. 2334682 with Double Sunk Illinois Triangle In Dial in a Dueber Gold Filled Case. The Illinois DS Triangle In Dial is in excellent condition with no visible issues and the Movement is very clean and beautiful, pictures don’t do it justice. This will make a wonderful addition to any Railroad Pocket Watch Collection. See my other auctions for more beautiful pocket watches and other unique and quality estate sale finds. I only have main springs replaced if they are broken to ensure they do run, but don’t necessarily keep perfect time.
