Serial Number 1326258 was reported as inaccurate.

Note: The serial number for my watch is 1326258. However
it is a Model 1879.based on the Waltham Watch
Movement Drawing #EA 25. The position of the train
jewels is key to identifying a 1879 movement vs a
1877 movement.
Curator Response: Thanks for the report. If possible, please upload an image of the movement to your collection for further evaluation and documentation.
