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.
The United States Watch Co. of Waltham, Massachusetts should not be confused with the more common American Waltham Watch Co. If the movement is NOT marked "U.S. Watch Co." or "United States Watch Co." please conduct a lookup under the American Waltham Watch Company.
