As we researched information for Pocket Watch collecting we have found the Serial Number tables for determining production dates to be helpful. We have gathered the relevant information which you can access by clicking the appropriate link displayed here.

Another tool we found to be quite helpful is the American Waltham Serial Number LookUp Tool provided by The National Association of Watch & Clock Collectors (NAWCC) available HERE.

All serial number information refers to the serial number of the
