Notes on Serial Number Data
Kundo Anniversary Clock
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.
