One of the most important and prestigious American watch manufacturers was the Gruen Watch Company, founded by a brilliant father-and-son team of horologists, Dietrich and Fred Gruen.
Serial number records are available for many of the old pocket watch companies like AM Waltham, Elgin, South Bend etc. The number you need is the serial number stamped on the MOVEMENT (i.e the inner workings).The reason: There have been a lot of watch manufacturing companies that have come and gone over the years.Many have gone out of business, while others destroyed records to save space. The new homepage graphics come from these materials. Have you discovered a box of Gruen stuff from a former employee and want to get more information about what you have??? Head over to the "About" page and leave feedback with your contact info. Gersch has been SO amazingly generous in their submission of photographs of materials saved by Richard after he left Gruen in 1954. You'll find the 88 page document on the page titled Did your parent work for Gruen??? I've helped several families figure out not only something about the items they own, but I can sometimes point them to employee newsletters that described what life inside the company.
