Serial Number 3000869 was reported as inaccurate.

Note: Model: 19
Curator Response: Thanks for the report. I have not found any original materials that support a Model 19 classification. Period material catalogs cover up to Model 18. I know Ehrhardt/Meggers designated the Model 19 as the version of the Model 18 with a Breguet hairspring, but it is unclear if they had original materials to support this or not. If you happen to have contemporaneous sources that identify the Model 19, please let me know. Either way, #3000869 appears to be fitted with a flat hairspring, which would be consistent with the Model 18 classification. Some of the surviving examples with serials 4,000,001+ do indeed appear to have Breguet hairsprings, but it is unclear if these were designated by the factory as a different model (pending further research).
