Notes on Serial Number Data
- 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.
- 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.
- 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.
- The record books appear to have been transcribed from working lists by clerks. Occasionally omissions and errors are noted.
- 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.
