 Notes on Serial Number Data

1. Most clocks are numbered on the case and the movement. These numbers in most all cases match, but occasionally movements were switched by the factory or the retailing jeweler.

2. The serial number record data shows the sale date of a given serial number. Prior to 1910 inventory control was not optimized and finished clocks remained in company inventory for years. The dates above show the average sale date for a given serial number. Specific clock sale dates may vary significantly.

3. Serial numbers were issued consecutively as movements were manufactured in groups of like type movements. These were then fitted to cases to meet special orders or for general stock.

4. The record books appear to have been transcribed from working lists by clerks. Occasionally omissions and errors are noted.

5. Prior to 1915 the record data lists serial number, date sold, customer, movement type, and case size, finish, and type. After 1915 case size, finish, and type were generally omitted.
