The data shown is a combination of information from the Waltham handwritten ledgers and the printed serial number list (the Gray Book). Gray book information is highlighted in silver gray. Be sure to enter the number found on the watch mechanism and not the one on the case. This database only lists information on watch movements, not cases.
