DATING INFORMATION

The information presented on this page is provided for reference purposes and is intended to help estimate a production period based on the historical data available. Serial-number dating alone does not constitute a means of authenticating a watch, a movement, or any of its components.

For Zenith, the information specifically refers to the caliber serial number. The production year of the caliber may differ from the year the watch was released.
