These timepieces represent a fusion of American horological craftsmanship and precious metal. They are mechanical time-telling instruments produced by the Elgin National Watch Company that incorporate a gold case, either solid or plated. An example would be a size 16 Elgin with a 17-jewel movement housed within a 14k gold filled case.
The significance of such items lies in their combination of functional timekeeping, aesthetic value, and intrinsic precious metal worth. Historically, owning a gold-cased pocket watch signified a certain level of affluence and status. The enduring appeal is partly attributable to the quality of Elgin movements and the lasting elegance associated with gold, making them desirable collectibles. Furthermore, their gold content can represent a tangible asset.
