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.

Company Timeline

April 1864

The Tremont Watch Co. is started in Tremont, Massachusetts by Aaron L. Dennison and A.O. Bigelow with a capital of $100,000. The concept of the company is to have certain parts manufactured in Switzerland and shipped to America. This strategy would offer the benefit of low labor costs and decreased factory expenses.

May 1865

The Tremont Watch Co. offers its first watch, a fully-jeweled 18s key-wind movement.

The Tremont Watch Co. is moved to Melrose, Massachusetts and renamed the Melrose Watch Co. At this time, it is decided to manufacture the entire movement in America. Mr. Dennison, the arcitect of the prior strategy to conduct the majority of part manufacturing in Switzerland, withdraws from the company. The remaining movements are refinished with the "Melrose Watch Co" name.


The Melrose Watch Co. runs short on capital and requests the stockholders to contribute more money. After this fails, Mr. Dennison returns to Boston, seeking to organize a new company to purchase the Melrose Watch Co. and factory.


After Mr. Dennison fails in creating a new company to absorb The Melrose Watch Co., the equipement is purchased by the English Watch Co. of England.
