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.

This is an early EH&Co, Series III Model 1862n movement with the balance-over-center-wheel, 3/4-Plate configuration. As described by Dr. Geller: "It has case screws on the dial plate, like the late, Model 1858 divided plate movements that immediately preceded it, and it also retains the late Model 1858 style of pallet bridge. It also features a Lange-style, hanging pin lever escapement, in which a single pin hangs down from the underside of one pallet arm and banks against the edges of a circular depression in the pillar plate. This borrowed idea was Howard's earliest experiment aimed at eliminating adjustable banking pins. The factory records indicate that this movement is fully adjusted to temperature, isochronism and positions, even though the factory did not begin engraving this type of information on watch plates until a few years later, after S# 12,000." See www.awco.org/Seminar2002/HowardTheme/h08.htm

The case is an entirely correct EH&Co made expressly for this style movement - case may be original to the watch. The dial is a scarce Type-3 variety with script signature. Hour and minute hands are likely original; seconds hand is probably a later replacement. Per Geller, approximately 40 1862n models are known to exist.
