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 "mechanism" of the watch).
  2. Never use the serial number from the case or any other part.
  3. Always select the correct manufacturer, which is usually stamped on the watch movement or dial.
  4. If the manufacturer is not listed on the site, you may have a "private label" watch or it may not be American-made.
  5. If the serial number includes a letter, enter it along with the number when using the lookup feature.
  6. 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.
  7. Consider uploading images of your watch by creating a collection account on the website. This is compeltely free and assists in promoting research in American horology.
  8. 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.

  • August 2, 2019:
    Serial Number 234431 was reported as accurate
  • July 25, 2019:
    Serial Number 233396 was reported as inaccurate
    Note: Just checking my records from many years ago and
    this watch was supposedly made in 1889, if thts of
    any help.

    I also believe its an 18,000 bph beat train.

    Thomass' first watch i was told was 1885.
    Curator Response: Thanks for the report. Estimated dates for Seth Thomas watches are difficult to pinpoint due to the company's practice of designating larger blocks for certain models. As a result, movements were not finished in a predictable order. Yes, the first Seth Thomas watch was introduced in 1885, and your estimated date of 1889 for this serial is reasonable.
