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.

Pocket Watch Crystal Size Chart & Calculator

Watch crystals protect the face of the watch from dirt, dust, and damage. After years of usage, it is common for crystals to become scratched, cracked, or even broken. Replacement crystal sizes are usually measured using the ligne unit system. Measurements are dictated by the case bezel dimensions, not the movement.

Carefully measure the diameter of the damaged crystal or the bezel opening with a micrometer. Enter the measurement above to calculate the nearest ligne size.

Size



Caution and precision should be duly excercised while fitting a replacement crystal, as some may measure slightly smaller or larger than the designated size. Therefore, the figures provided on this page are to be used as a general guide. It is advised to carefully measure the size of the bezel, bezel opening, and crystal to assure a proper fit.

In addition to diameter, the crystal height should also be considered when searching for a replacement. Typically, heights are designated on a scale from 1 to 8. Sizes 6, 7, and 8 are usually best for hunting cases.
