Use the movement serial number, not the case stamp
American pocket-watch movements often carry a maker name and movement serial, while the case may have been manufactured by another company and carries its own numbering. A case number cannot reliably date a movement using the maker’s movement database.
Photograph the movement under even light, including engraving and layout. Match the exact maker and movement grade in a reputable reference. Re-cased watches are common, so the case, dial and movement may not have begun life together.
