Pocket Watch Database

We noticed that you entered a relatively short serial number.
"927" could possibly indicate the grade of the watch and not the serial number of your movement. Serial numbers are usually more than a few digits.

Due to the lack of existing factory records, our U.S. Watch Co. (Waltham, Mass) database has been reconstructed using observations of known watches.
As a result, the information may contain inaccuracies. Please let us know if you have details that can improve the database.
