Evolution of Corliss Patented Stem Winding and Setting Designs

As we close out the study of Charles P. Corliss, we take a look at the evolution of his patented stem winding and setting designs. From the 1885 patented design found on the 18-Size interchangeable movements to the elegant solution implemented on the 16-Size “Model 1895,” they all feature characteristic elements of Corliss’ ingenuity.

While most engineering conversations related to the Elgin National Watch Company focus on the likes of Moseley and Hunter, Corliss deserves mention as one of the key figures in the company’s history – certainly fitting for an individual nicknamed “Father Time” while working at one of the largest watch factories in America.
