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:

The Grade 83 was one of the most popular products of the Rockford Watch Company with over 20,000 sold. This affordable mid-grade option offered customers a great value, and many private labels are found marked on Grade 83 movements. The grade was available as unadjusted (Grade 83) and adjusted to temperature (Grade 83x), though no differentiation is indicated in the Rockford Serial Lists. In the 1896 A.C. Becken catalog, the adjusted Grade 83x was sold at a $4.00 premium over the standard Grade 83. By 1899, the Grade 83x was no longer offered in the annual A.C. Becken catalog. However, the standard Grade 83 could still be purchased for $11.70. Despite the different levels of adjustment, all Grade 83 movements were fitted with a micrometric regulator. Early runs feature the "Type 4" regulator while later runs feature the "Type 5" and then the "Type 6" near the end of the Grade 83 production.

With 32 distinct runs, the Grade 83 is one of the best-sellers in the history of the Rockford Watch Company. Observations have confirmed that most runs are consistent, featuring nickel plates, 15 Jewels, and a micrometric regulator. Adjusted (Grade 83x) and Unadjusted (Grade 83) movements are mixed in a variety of runs. One run [286,001-286,200] is comprised of movements featuring an elegant two-tone finish, some of which are marked "Adjusted." The two-tone Grade 83 movements are uncommon, with an estimate production of 200.

One run [417,501-418,000] is designated as featuring 17 Jewels instead of 15 in the Rockford Serial Lists. A thumbnail image of movement #417655 appears to show that the center wheel is not jeweled. Other Grade 83 runs are listed as featuring 15 Jewels, and various observations have supported this. #417681 has been verified as marked "17 J" with features more consistent with the Grade 82. If the entire run was actually finished as Grade 82, production estimates would need to be revised accordingly.
