I recently received my paternal grandfather's 1911 Hampden pocket watch for Christmas. A local jeweler, who advertise as repairers or antique pocket watches, had restored it to working order before it was gifted to me. I just learned that my maternal grandfather also owned a pocket watch, not in working order, and it was also given to me. As you can see it is missing the crown and stem. I am unsure what other repairs are needed. Any help in identifying this model would be appreciated as information on the Roamer is not as easy to find as the Hampden. Any help would be appreciated as this has really sparked an interest in antique watches.
