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.

Research Notes:

According to factory serial lists, the Rockford Grade 81 was produced in six runs with inconsistent features. In the 1896 A.C. Becken catalog, the Grade 81 is described as being fully adjusted and is paired with the No. 61 (Openface) movement. By 1899, neither option was offered in the annual A.C. Becken catalog. Understanding of the Grade 81 traits is quite vague. The first run [245,001-246,000] is designated in factory serial lists as an 18-Size Model 3 with 9 Jewels and Gilt plates. Observations in this run have confirmed this description. Following a large gap, the Grade 81 returns for a second run [415,001-415,200], this time listed as an 18-Size Model 8 with 17 Jewels and "Plain" finish. The remaining runs are consistent with these traits with the exception of the finish designated as "Nickel" for the second-to-last run [439,651-439,700]. Observations of actual production causes additional confusion. Movements recorded in the second run are damaskeened nickel, marked "R.W.Co. - Rockford, Ill. - 17 J - Adjusted." Observations from the runs following indicate a two-tone finish was applied despite the "Plain" or "Nickel" finishes listed in the serial lists. This two-tone finish is consistent with the 1896 A.C. Becken catalog description. Additionally, multiple movements from the third-to-last run have been verified as marked "21 Jewels" (likely the first 100 of the run).
