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 Mozart Watch Co. is organized in Providence, Rhode Island with a capital stock of $100,000. The company is proposed to manufacture a unique 18s movement known as the "Three-Wheeled Mozart," invented by superintendent, Don J. Mozart.


Don. J. Mozart is successful in obtaining a capital stock of $200,000 to begin the new company.


The "Three-Wheeled Mozart" proves to be unsucccessful, and the stockholders of The Mozart Watch Co. decide the company must start producing a regular 18s 3/4-plate movement in order to survive. Mozart is ousted from the company, and L.W. Cushing replaces him as superintendent. The company is then renamed the New York Watch Co. Don J. Mozart moves to Ann Arbor, Michigan to start a company to continue production of his "Three-Wheeled Mozart" watch.


After only manufacturing roughly 30 movements, The Mozart Watch Co. ceases operations and the company equipment is sold to Rock Island Watch Co. for $40,000 and $25,000 in stock. The existing movements are finished and given to the stockholders and friends of the Mozart Watch Co.


After the Rock Island Watch Co. moves the purchased equipment to Milan, Illinois, they decide it is not what they need and refuse to pay the $15,000 note to The Mozart Watch Co. After arbitration, the equipment originally sold to the Rock Island Watch Co. is repossesed along with a payment of $5,000.


The Freeport Watch Manufacturing Co. purchases the factory equipment from the Mozart Watch Co. for $1,000 cash and $50,000 stock.
