Illinois Watch Co. was in operation from 1869-1948 and produced some of the most renowned railroad-grade movements ever manufactured. Watches were produced in their factory in Springfield, Illinois.
This dial features a guilloché center finished in gilt with golden numerals cut directly into the dial. The intricate pattern at the center reflects light differently depending on the angle, giving the dial a constantly changing appearance. Framing the dial are original heat-blued kite hands, whose rich blue tone provides exceptional contrast against the warm gilt finish. Beneath the dial is Illinois’ Grade 405, a 17-jewel in-house movement manufactured in Springfield, Illinois, in 1925. Every component of the movement was carefully restored by hand. The screws and steel hardware were thermally blued using traditional watchmaking techniques to improve corrosion resistance while adding depth and contrast (read more here). The jewel settings, gear train, balance, and balance weights were individually hand polished to restore their original golden tone. Together, these details create a singular example of Illinois design and craftsmanship—thoughtfully restored and ready for a new century of wear.
This Illinois timepiece is housed in our precision-engineered 316L stainless steel conversion case, built for both durability and comfort. Adjustable lugs allow effortless winding and setting while tailoring the fit to a wide range of wrist sizes. Front, back, and crown gaskets provide water resistance up to 50 meters (though we recommend removing the watch before water activities). Fully serviced and tested, this piece is ready to be worn and enjoyed for years to come.
