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:
Always input the serial number from the pocket watch movement (the "mechanism" of the watch).
Never use the serial number from the case or any other part.
Always select the correct manufacturer, which is usually stamped on the watch movement or dial.
If the manufacturer is not listed on the site, you may have a "private label" watch or it may not be American-made.
If the serial number includes a letter, enter it along with the number when using the lookup feature.
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.
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.
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.

ELGIN WINDING INDICATOR
Diagram of Elgin Winding Indicator
I-IE ELGIN WINDING INDICATOR is of the posi‐ tive motion type. It consists of a planetary gear, with three radiating trains, one of which connects with a winding wheel, another with a member of the time train, and the third with the indicator handAonly eleven parts
in all, exclusive of screws.
The moving parts of the Elgin Winding Indicator are all toothed wheels; there is no slipping friction, nor is there a n y necessity for disengaging the indicator while setting the hands of the watch, and consequently the indicator hand c a n never get out of its proper relation to the winding and time trains. '
Referring to the diagram, the planetary gear is the one which carries two small wheels ( o n e on either side) that revolve on the same axis at some distance from the axis of the gear itself; the larger of these two small wheels is driven directly by the train, which con‐ nects with the winding or “main” wheel, and indirectly by the rotation of the planetary gear about its axis; the smaller drives the indicator hand train. The two small wheels, being fast on the same shaft, always turn to‐ gether, so that, whether the larger o n e is turned by the winding of the watch, or by the rotation of the planetary gear through its connection with the time train, (both of which actions m a y be going on at the same time,) the indicator hand is certain to move correspondingly and indicate the true state of the winding.
