Identifying a vintage pocket watch, with few exceptions, is easy and requires few or no tools. Vintage pocket watches from the late 19th century through the 1950s are well marked with the watchmaker’s logo embossed on the dial and engraved on the movement. Often the watchmaker’s name will also be engraved on the inside of the case back. However, some Swiss watchmakers imported unassembled watches with no markings to the U.S. to be assembled and sold by independent sellers or department stores. These watches are difficult, if not impossible, to identify.
