Waltham, Elgin, Hamilton, Illinois, and maybe a few others comprise the cadre of "fine U.S. watch manufacturers," as it concerns vintage watch collecting. This is a non-functioning hex-case Waltham, from perhaps the 1920s or 1930s. It uses a bi-metallic balance, which were in use until the late 1930's or early 1940's. This is a good example of the certain (cont.)
special touches you could find on a watch from that period. Note the case engraving on the side by the crown. The onion crown itself is substantial and easy to grip. The crystal is glass.
