How to Find Info About Your Pocket Watch

The Pocket Watch Database has compiled data covering the major American pocket watch manufacturers and created an easy way to find information using the serial number on the watch movement. Here are a few tips to find information about your pocket watch:

  1. Always input the serial number from the pocket watch movement (the "guts" of the watch).
  2. Never use the serial number from the case or any other part.
  3. If the serial number includes a letter, enter it along with the number when using the lookup feature.
  4. Many pocket watch case backs screw off. Others may require a dull wide blade to pry or pop the cover. Be careful not to scratch or damage the movement.
  5. Always select the correct manufacturer, which is usually stamped on the watch movement.
  6. If the manufacturer is not listed on the site, you may have a "private label" watch or it may not be American-made.
  7. Understand that many companies did not keep accurate or complete records. As a result, information displayed on this site may have inaccuracies. This is to be expected, and we have included an option to report inaccurate information on the result pages so the database can be continually improved.

    Note: RR Grade is a no.
    Hamilton's Grade 934 was not originally sold as
    nor was it considered by them to be a Railroad
    Grade movement, that designation is what counts
    heavily to most collectors. The "Adjusted" on a
    934 meant "Adjusted to Temperature" but not to the
    "5-Positions" required of a Railroad Grade
    Movement.
    Easy to remember this fact, Hamilton did not
    market any 18-size grade number below 936 as a
    Railroad Watch. The Grade 936 was their first RR
    Grade Watch,
